I know, Jackson turns 30 in July - that hasn't always been the best age for a running back in terms of statistical production. But there is nothing but upside for him in Atlanta. The veteran had rushed for 1,000-plus yards in eight straight season with the St. Louis Rams, and I think he'll reach that total with ease in 2013. The advantage to playing in a prolific offense is additional touchdown opportunities, which is something he didn't see enough of during his time in St. Louis. He won't be drafted as a No. 1 fantasy runner, but Jackson is going to be tough to pass as a high-end two. (AP Photo/David Tulis)

No Wes Welker, no problem with the Patriots. The team added a younger version in Amendola, who now has all kinds of breakout potential with future Hall or Famer Tom Brady throwing him the football. The Texas Tech product has enormous statistical potential in an offense that has almost always been beneficial to the slot receiver. The one downfall with Amendola is his proneness to injuries - he's missed a combined 20 games over the last two years due to an assortment of ailments. So while there is some risk involved, Amendola has No. 2 value and No. 1 potential in all PPR formats. (AP Photo/Paul Spinelli)

I was high on Harvin far before he was ever traded to the Seahawks, and I like him even more now that he's in the Great Northwest. At 24 and just entering the prime of his career, the Florida product has a pile of statistical upside in what could turn into an explosive offensive attack. Harvin also sees a nice upgrade at the quarterback spot, as he'll now be catching passes from young upstart Russell Wilson. Fantasy leaguers should be looking at Harvin at some point in the second or third round as a No. 1 wide receiver - he's a definite candidate to have a real breakout campaign.

Remember the sort of numbers Bush recorded as a receiver out of the backfield while a member of the New Orleans Saints? Well, we could see him get back into the 60-70 catch range now that he's with the Lions. The playmaking veteran out of Southern California will no doubt lose some work in short-yardage and goal-line situation to Mikel Leshoure, but he should lead the team in backfield touches overall (barring injuries). Fantasy owners should consider him in the middle rounds as a No. 2 or 3 runner in standard leagues and a surefire two in those formats that reward points for receptions.

Mendenhall has a lot going for him as a member of the Cardinals. He's playing for coach Bruce Arian (his offensive coordinator for a time in Pittsburgh), who prefers to utilize one featured back and has already referred to the veteran as a three-down back. The Illinois product is also in a contract year - he signed a one-year deal - so there will be some added motivation for the 25 year old. Of course, the Cardinals have major question marks both at quarterback and on their offensive line, so it's not all roses. Right now, Mendenhall has flex-starter appeal in 2013 drafts.

Myers is coming off his best statistical season with 79 catches, 806 yards and four touchdowns as a member of the Oakland Raiders. Now with the Giants, Myers is clearly the favorite to start ahead of Adrien Robinson. While his blocking skills leave something to be desired, Myers is a sure-handed pass catcher who should push 60-plus receptions in an offense that has been good to tight ends - just look at the numbers of Jeremy Shockey and Martellus Bennett. A viable No. 1 tight end across the board, Myers will be worth a middle-to late-round selection in all standard and PPR formats. (AP Photo/Tony Avelar)

Cook has long been considered a fantasy sleeper, but he's failed to meet those expectations. Now in St. Louis, though, the South Carolina product is going to be in a nice position to find success. The Rams have lost Amendola and Brandon Gibson as a free agents, and the team clearly isn't enamored with Lance Kendricks to give Cook a bountiful five-year contract. With the promise of a great role in the pass attack, Cook could push into the top 10 fantasy players at his position next season. He should be targeted in the late rounds as a high-end No. 2 fantasy tight end with major potential. (AP Photo/Joe Howell)

Welker recorded 100-plus catches in five of his six seasons with the Patriots, but fantasy leaguers should expect him to see at least a slight decline in production with Demaryius Thomas and Eric Decker in the mix. In fact, both Welker and Decker should be seen as No. 2 fantasy wideouts rather than No. 1s at this point. The fact that he'll have a future Hall of Famer like Peyton Manning throwing him the football is an obvious positive, though, and it's possible (if not likely) that he'll throw the football 600-plus times in 2013. Overall, Welker should be drafted in the middle rounds. (AP Photo/Ed Andrieski)

In each of the two seasons prior to 2012, Wallace had finished in the top-10 in fantasy points among wide receivers. Of course, that was a member of the Pittsburgh Steelers and with Ben Roethlisberger throwing him the football. Now in South Beach, he'll become the team's new No. 1 wide receiver with second-year quarterback Ryan Tannehill under center. While I don't exact love the fit, Wallace's youth and nose for the end zone - he's scored a combined 26 times in the last three seasons - makes him a viable No. 2 fantasy option in most drafts. He'll come off the board in the middle rounds. (MiamiDolphins.com)

Once considered an elite No. 1 fantasy wideout, Jennings has seen a decrease in value with the Vikings. First, the drop off at quarterback from Aaron Rodgers to Christian Ponder is enormous. Second, one has to be at least a bit concerned about the fact that Jennings has missed a combined 11 games over the last two seasons due to injuries. What's more, Jennings had more career receptions (65) receiving yards (964) and touchdowns (10) against Minnesota during the regular season than any other opponent. He's now a borderline No. 2 or 3 fantasy wideout regardless of the format. (Ben Liebenberg/NFL)

Keller is coming off an injury-riddled season that saw him mis eight games while points some of the lowest numbers of his career. His move to Miami should be a positive one, though, as Keller will be in a contract year and motivated to produce. He'll be drafted as a No. 2 tight end, but Keller could bring back low-end No. 1 value. (AP Photo/Damian Strohmeyer)

Greene finished a respectable 15th in fantasy points among running backs last season. Unfortunately, he has virtually no chance to duplicate that level of success with the Titans. While he will clearly have a role in the offense, Greene won't be supplanting Chris Johnson as the team's top running back. He's worth just a late rounder. (AP Photo/Scott A. Miller)

You might now know it, but Woodhead finished in the top 25 in fantasy points among running backs in 2012. Now a member of the Chargers, he'll be a change-of-pace and third-down back behind Ryan Mathews. While he will have added value in PPR leagues, Woodhead won't have much more than late-round draft value in most formats. (AP Photo/Damian Strohmeyer)

As I mentioned earlier, Bennett is coming off his best statistical season during a very short stint with the Giants. That alone will make him worth a late-round look as a No. 2 fantasy tight end in 2013. However, just keep in mind that Chicago has been a sort of statistical abyss for fantasy tight ends throughout the years. (AP Photo/Charles Rex Arbogast)

Boldin was a postseason star for the Baltimore Ravens during their Super Bowl run, but his regular-season totals were average. In fact, he's failed to post even 950 yards in the last three years. Now with the Niners, he'll be no better than the third option in the pass attack and worth a late-round look in most leagues. (AP Photo/Ben Liebenberg)
