If we evaluate JaMarcus Russell based on his three years in the NFL, he would be unanimously regarded as the biggest bust in NFL history.
That being said, NFL teams have never avoided giving second chances to talented players. Although his first three seasons aren't indicative of a budding prospect, there's no doubt that JaMarcus Russell's natural ability is worthy of a second chance.
When JaMarcus gets his second chance, the biggest question will be whether he has the motivation required to become an NFL caliber quarterback.
JaMarcus Russell wouldn't be the only first overall selection to rebound from a disastrous introduction to the NFL. Jim Plunkett, first overall selection by the New England Patriots in 1971, struggled with his first and second team, before leading the Raiders to two Super Bowls.
