Round 1, Pick 2: Greg Robinson, OT, Auburn
If I'm making the pick, I'm willing to consider Sammy Watkins here based on need, and would also certainly consider the option of moving down a few spots if the offer is rich enough. But Robinson is one of the better offensive linemen to enter the draft in years, with the upside of an All-Pro at left tackle, capable of neutralizing the best pass-rushers and absolutely mauling defenders in the run game. St. Louis can select him knowing an impact wide receiver is still going to be available at No. 13 (and even beyond that given the depth at the position).
Round 1, Pick 13: Darqueze Dennard, CB, Michigan St.
I'll get pilloried here for not making this a wide receiver, but do remember this is a very deep draft at that position, and getting the cornerback with the most diverse skill set in the draft would also really help this team. Dennard is ready to help an NFL team at a position where rookies tend to get beat up pretty bad early on as they adjust to the speed and talent level of NFL wide receivers. But Dennard can play on or off, attacks the backfield as a run defender, and can mirror routes as well as any CB in the draft. Yes, I think this could be Odell Beckham, too. We'll see.
Round 2, Pick 12: Jimmie Ward, S, Northern Illinois
Ward can be special in coverage and fills a need for the Rams, as he can pair with the now healthy T.J. McDonald to shore up the back end of that defense.
