Suh will participate in the Combine..Ricky Sapp has issues

The agent for Nebraska DT Ndamukong Suh confirmed that his client will participate in on-field events at next week's Combine.
"He's in the best shape of his life and he wants to (demonstrate) that to people," said Suh's agent. "He's ready for it all." Suh will take part in the forty-yard dash, shuttle drills, and weightlifting. Though he has more to lose than gain as one of the draft's consensus top-two or three prospects, Suh's performance should only reinforce that he's going to be a dominant pro.

I love that from Suh, he has everything to lose and not much to gain and is going to do it anyway...great great sign that Suh will be a NFL player for a long time...he loves this stuff.

Some not so good info about Ricky Sapp:

Clemson DE Ricky Sapp reportedly missed last month's Senior Bowl due to lingering effects from the ACL surgery he underwent in 2008.
Sapp, a borderline first-round prospect, didn't miss a game as a senior but reportedly played at only 65%. His initial rehab was apparently not handled right by Clemson and resulted in Sapp dealing with quadriceps problems in '09. This explains Sapp's pedestrian senior-year numbers (five sacks, 15 TFL). He is expected to be at or near full speed by next week's Combine.

Awful break for Sapp, Sparano and co really believe in their rehab process for ACL's, Sapp leaned on the Clemson staff and it turned out poorly for him.

I'm no Dr. however it seems to me that sooner or later Sapp will need more knee work done.
