Hamstring tweak won't drop McClain

Editor's note: All 40-yard dash times listed below are unofficial unless otherwise noted. Scouts Inc.'s daily combine buzz will include as many official numbers as possible and expanded takes on players mentioned in the blog.

• We're a little disappointed by Alabama ILB Rolando McClain's decision to opt out of combine workouts, but reports indicate McClain has been nursing a hamstring injury for a few weeks. McClain is our top-ranked inside linebacker and Alabama's pro day is now his only chance to showcase himself for NFL scouts.

However, McClain's biggest strengths on film are his instincts and tackling ability rather than raw athleticism. This decision won't hurt him much in the long run because he was not expected to turn in a jaw-dropping performance anyway.

• Georgia Tech DE Derrick Morgan stood out in a drill designed to simulate alternating between shedding stand-up blockers and fighting off cut blocks. While his punch could have been more violent he stayed low and looked smooth getting down the line.

• Tennessee DT Dan Williams showed heavy hands and above-average upper-body strength while slapping and ripping though big bags today. Like Morgan, Williams' punch could be more compact and sudden but he still had a strong performance.

• Massive Alabama DT Terrence Cody has shed some weight but still ran the slowest 40-yard dash time of his group at 5.68 seconds. In fairness, though, Cody's 40 time doesn't much matter because he will primarily be occupying blockers and eating up space in the middle of the 3-4 defense.
