Top Picks Analysis: The Rams were expected to tab the draft's best offensive tackle in Greg Robinson at No. 2 overall but they followed that up by snaring the best defensive tackle with the 13th pick, Pittsburgh three-technique Aaron Donald.

Robinson is so athletic that many project him as the next Orlando Pace in St. Louis, while Donald is a bit undersized but has such great quickness that some have compared him to John Randle, the former Minnesota Vikings star who is now enshrined in Canton.

Teaming Donald, who should have been a top-10 pick, with ends like Robert Quinn, perhaps the best pass rusher in all of football, and Chris Long is sure to give Russell Wilson and Colin Kaepernick some sleepless nights in the ultra-tough NFC West.

"We're a lot better now," Rams coach Jeff Fisher said. "We all know what Greg (Robinson) is capable of doing. He's an outstanding young man. We'll plug him in where we feel he's got the best chance to be successful right now. We don't know exactly where that is, but he may start out inside before we move him back outside. You talk about an athlete. Powerful, quick, great quickness and strength. He's got a chance to be a dominant player inside initially.

"Then of course, Aaron (Donald) is very, very productive; he's an outstanding young man. He's way ahead in hand use on the line of scrimmage. He does an outstanding job with his hands."

St, Louis was also able to add talented Florida State cornerback Lamarcus Joyner, who should project in the nickel right away, in the second round, and Auburn runner Tre Mason, a very solid north-south runner, in the third.

Best Value Pick: It's tough to call the 13th overall pick value because he is supposed to be good but Donald was probably the sixth best player in this draft.

Questionable Calls: Michael Sam might have been a big story to the national media but at the end of the day, the Missouri defensive end is a classic tweener, lacking the length to be an impact player at defensive end and the lateral mobility to play in space as an outside linebacker.

Summary: Robinson became the eighth player taken by the Rams with the picks acquired from the Robert Griffin III trade and he may end up being the best of them all. Meanwhile, Donald has Pro-Bowler written all over him, while Joyner and Mason could be contributors in short order.
