Louisville quarterback Teddy Bridgewater has announced that he will forgo his senior season with the No. 18 Cardinals and enter the NFL draft.Projected as a first-round selection and possibly the first QB taken this spring, Bridgewater passed for 3,970 yards and a school-record 31 touchdowns this season, including a career-best 447 yards with three TDs in Saturday's 36-9 rout of Miami in the Russell Athletic Bowl.Bridgewater said in a release that the decision "was extremely difficult," but said that attending Louisville "was one of the best decisions I could have ever made."The Cardinals won 27 games with Bridgewater starting, including 12 this season to tie a school record. The highlight was last year's 33-23 Sugar Bowl upset of Florida in which the Miami native earned MVP honors.
