Five big NFL draft boo-boos

Here's a list of NFL draft busts that should make every general manager nervous when the league's draft gets underway today:

1. QB RYAN LEAF: He was considered to be at least the equal of Peyton Manning when they entered the 1998 draft. Washington State's Leaf went to the Chargers with the second overall pick and immediately flamed out, throwing 33 interceptions and 13 touchdowns. Colts breathing sigh of relief ever since after taking Manning with the top pick.

2. QB HEATH SHULER: Had a great career at Tennessee, but was a flop with the Redskins after they took him with the third overall pick in 1994. An injured shoulder and rookie-season holdout didn't help him. He came back, though: He's now a U.S. Congressman from North Carolina's 11th district.

3. LB BRIAN BOSWORTH: “The Boz” entered the league in 1987 overhyped and overinflated (he had steroid issues at Oklahoma). Taken by Seattle in the first round of the supplemental draft out of Oklahoma, he's best remembered as a pro for being run over by Bo Jackson on Monday Night Football.

4. OT TONY MANDARICH: Taken No.2 overall by the Packers in 1989, he has since admitted that he, too, took steroids at Michigan State and in his early days in the NFL. Had an up-and-down (mostly down) career with Green Bay and Indianapolis.

5. QB TIM COUCH: Left school after his junior season at Kentucky and was taken No.1 overall in 1999 by Cleveland. That's as good as it got for Couch, who threw 64 touchdowns and had 67 interceptions for the Browns (he also fumbled 37 times).
