St. Louis Rams will be picking No. 15 in 2016 NFL draft

Here's a quick look at the top three positional needs for the St. Louis Rams:

Quarterback: Whether it was Nick Foles or Case Keenum, the Rams had the least productive quarterback group of any team in the NFL in 2015. The Rams won some games at the end of the year with Keenum, but an upgrade that can give them something closer to league-average production for an entire season would go a long way in helping improve an ailing offense. It seems unlikely the Rams will be in position to get a top signal-caller in the draft, so maybe they can find help in free agency. But one way or another the Rams need to bring in someone from the outside to compete for the job.

Wide receiver: For the second consecutive year, Kenny Britt led the Rams in receiving yards, but his production actually declined from 2014 as he finished with 681 yards. For perspective, Britt's total ranked just 57th in the NFL among all pass-catchers. The Rams haven't had a receiver with at least 800 yards, let alone 1,000, since Torry Holt in 2007. As a group, Rams receivers posted 137 catches for 1,635 yards (last in the NFL) and eight touchdowns. To put that into context, Atlanta's Julio Jones finished with 136 catches for 1,871 yards and eight touchdowns. The argument can be made that with better quarterback play, the Rams' receivers would improve, too, but the opposite is also true. And with Brian Quick and Wes Welker headed for free agency and Stedman Bailey facing an uncertain future after he was shot twice in the head, the Rams need to prioritize finding a true difference-maker at this position, even if it goes against their run-centric philosophy.

Offensive line: After a rough start, the Rams' offensive line improved toward the end of the season, especially after it finally found some much-needed stability. The Rams have some pieces along the line that should be solid moving forward, players like right tackle Rob Havenstein and guard Jamon Brown. And youngsters like guard Cody Wichmann and Andrew Donnal could, at minimum, provide some depth. But the Rams still have some questions that need to be answered. They could use an upgrade at center and they must decide if they want to bring oft-injured Rodger Saffold back at a cap charge of almost $6 million. Greg Robinson is still in place, but the Rams need improvement from him in Year 3, too, or they might have to consider moving him back inside and searching again for a left tackle.
