If you're a smart head coach or general manager, then for the last five weeks, since the NFL draft reached its conclusion, you've been studying or, at the very least, pondering your next move. Because your're not finished trying to find the next crop of talent for your franchise.

Typically, the draft comes to an end, and almost instantly it triggers the run on undrafted free agents. This year, teams have had time to think it over, with the lockout putting business as usual on hold. The goal is still the same, though: You hope to find yourself the next Kurt Warner, or the next Warren Moon, or the next John Randle.

Or, more recently, the next Tramon Williams. The Green Bay Packers' undrafted cornerback out of Louisiana Tech found his way in his fifth season to make the Pro Bowl in 2010. Not only that, but Williams was instrumental in Green Bay's playoff march to the Super Bowl, coming up with the game-sealing interception against the Eagles in the wild-card round and a big-time 70-yard interception return for a touchdown in the divisional round at Atlanta.

When you make big plays like that, you get noticed, as you'll find that Williams is now included in my list of the 100 greatest undrafted free agents of all time.
