Ideally, only the truly elite, Adrian Peterson-level running backs are selected in the top five, which is why I maintain that despite his immense talent and physical attributes that create puddles of scout drool, the Browns shouldn’t take Trent Richardson with their fourth overall pick.

By making that pick Cleveland is essentially saying that they’re confident one player can account for around 40 percent of their offense, and that player is a running back during the middle of a passing renaissance in the NFL. Richardson could very well achieve that percentage, but the health risk at running back is far too great.

He may be too much to resist, though, especially if the Browns are easily persuaded by physical harm

That’s Richardson at Alabama’s Pro Day today demonstrating his blocking strength by sending Browns running backs coach Gary Brown tumbling onto his posterior. It didn’t quite match Nate Solder’s demonstration of demolition during his Pro Day last year, but Richardson is still your early clubhouse leader for the best Pro Day moment of 2012.

We should have expected this from a freakish behemoth who can fend off multiple humans in his front yard…

Richardson had his knee scoped in January following an injury during Alabama’s national championship win over LSU, and he didn’t participate in any Combine events.

That’s why he was closely monitored today during Alabama’s second Pro Day, and while his 40-yard dash time registered different digits on nearly every one of the 91 stopwatches, NFL.com lists his best time at 4.45. He also had 25 reps at 225 pounds in the bench press.
