Miami (Fla.) offensive tackle Seantrel Henderson is one of the more confounding prospects in this year's draft: He has a ton of natural ability and athleticism but not much of a track record. Thursday's pro day was just as confounding.
Miami's pro-day workout was not open to the media, but there were reports that Henderson quit late in the workouts. However, his agent, David Levine, told the South Florida Sun-Sentinel that Henderson "went there intent to do the bench and position drills, but his competitive spirit took over and he did a full combine. At the end of the workout he got dehydrated, started getting a super bad headache, felt like he was going to throw up and didn't do the last two O-line drills."
Levine also told the Sun-Sentinel that Henderson improved his vertical jump (28.5 inches, from 24 inches) and broad jump (8-foot-6, from 7-9) from February's NFL Scouting Combine.
And the Sun-Sentinel quoted an NFC executive saying, "He did everything we needed to see. He just looked pretty winded at the end, but they put them through it."
Henderson was a consensus top-three player nationally out of high school in Minneapolis in 2010, but he started just 24 games in his UM career (nine of those came in his freshman season) and coaches knocked him for his lack of consistency and focus. In addition, while he is considered a prototype left tackle, he played mostly on the right side for Miami.
Henderson started six games in 2013 at right tackle and missed one game because of a suspension; it was the third time in as many seasons that Henderson missed at least a game because of a suspension. He said in January that marijuana use led to some suspensions.
At February's combine, Henderson measured in at 6-foot-7 and 331 pounds and ran the 40-yard dash in 5.01 seconds, including a 10-yard split of 1.71 seconds. At the time, NFL Media draft analyst Mike Mayock said Henderson has "first-round talent," but he also said Henderson has "a lack of consistency both on and off the field" and could go anywhere from the second to the seventh round.
Henderson might be at the very top of the "buyer beware" list in this draft. He has the potential to be a dominant lineman, but he also could be a wasted draft pick. Given his baggage, a team is taking an unnecessary risk if it selects him before the third day (Rounds 4-7) of the draft.
