Phillips's run-ins with the law overshadowed his breakouts on the field. In two seasons in St. Louis he spent 23 days in jail for DUI. He retired in 1999 and is serving 31 years for assault.
3 Tony Mandarich
T Packers (No. 2 in 1989)
SI tabbed the 6' 6", 315-pound Michigan State senior as "the best offensive line prospect ever." Oops. Turns out, steroids played a large part in Mandarich's size and prowess. Alcohol and painkillers didn't help his progress, and Green Bay released him in '92.
2 Ryan Leaf
QB Chargers (No. 2 in 1998)
Leaf's most notable performance in the NFL was his profanity-laced "Knock it off" tirade at a reporter during his rookie season. In 18 starts with San Diego he lost 14 times, throwing 13 touchdowns and 33 picks. He's currently serving a seven-year sentence in Montana for drug possession and burglary.
1 JaMarcus Russell
QB Raiders (No. 1 in 2007)
After Russell held out through training camp and the preseason, Oakland signed him to a contract worth $61 million, with $32 million guaranteed. He returned the favor by going 7--18 in three seasons.
