Jay Glazer of FOXSports.com reports the St. Louis Rams have signed first overall pick Sam Bradford to a six-year contract.

According to multiple reports, Bradford's contract has a base value of $78 million dollars, and tops out at $86 million dollars. $50 million dollars is guaranteed.

Bradford started 31 games at Oklahoma, completing a school-record 67.6% of his 893 pass attempts for 8,403 yards and 88 touchdowns, also tops in Sooners’ history. Bradford won the Heisman Trophy in 2008, but opted to remain in school for the 2009 season.

Bradford injured his right shoulder in the season-opener, and missed three starts while rehabilitating his injury. After passing for 389 yards and a touchdown in his first game back, Bradford re-injured his shoulder the following week against Texas, ending his season and college career.

The red-shirt junior announced that he would have season-ending surgery and that he would forgo his final season of eligibility and enter the 2010 NFL Draft.

With questions about his durability and arm strength following shoulder surgery, Bradford measured in at the Combine at 6-4 and 236 pounds, up nearly 15 pounds from his playing weight in college. Bradford did not do on-field workouts at the Combine, but held a public workout for NFL talent evaluators on March 30, and worked out privately for NFL teams before the draft, where he answered any questions teams had about his arm strength.

Though veteran A.J. Feeley is listed as the top quarterback of the Rams’ depth chart, Bradford will get every opportunity to earn the starting job this summer, and it would be surprising if Bradford is not in the starting lineup by mid-season
