Four quarterbacks were taken in the first round of the 2012 NFL Draft, and each one will begin the season as a starter. But the signal-callers face different expectations based on their landing spots. Bucky Brooks will take a look later Tuesday at the outlook for Ryan Tannehill, Andrew Luck, Robert Griffin III and Brandon Weeden as they enter their first year in the NFL.
Here's what else is on tap Tuesday:
» Gil Brandt takes a look at the AFC and identifies two players -- one on offense and one on defense -- for each team who must step up this season.
» The Buffalo Bills cut ties with defensive end Shawne Merriman on Monday. Gregg Rosenthal says it's fair to wonder whether "lights out" now also might apply to Merriman's NFL career.
