Details of Jared Cook's contract with the St. Louis Rams have been released, per The Tennessean's Jim Wyatt.

This marks an ugly end to Cook’s career with the Tennessee Titans and a chance to start fresh in St. Louis.

The 25-year-old was a third-round draft pick in 2009 and showed the ability to be a dynamic receiving threat. At 6’5” and 248 pounds, he has the size to dominate smaller players, but he also has the athleticism to stretch defenses.

As the tight end position continues to evolve in today's pass-oriented NFL, that combination is a valuable commodity.

His best season came in 2011 when he caught 49 passes for 759 yards and three touchdowns. Last year, he racked up 44 receptions for 523 yards and four touchdowns before his campaign ended early due to a torn rotator cuff.

But Cook, like the Titans’ passing game in recent years, has been inconsistent. This led to frustration at times during his tenure in Tennessee, and he requested to be traded during last season.

The franchise opted to hold on to him and let him play out his contract, and now he will join former Titans coach Jeff Fisher in St. Louis. Fisher was still in Tennessee when the team drafted Cook.

Sam Bradford will be happy to have him, as the former No. 1 pick could use another receiving threat. St. Louis ranked 18th in passing yards last season while Bradford ranked 18th in passer rating.

The Rams need more weapons on offense in order to help Bradford live up to his potential, and this is certainly a step in the right direction.
