Connor Barwin, DE/OLB
Connor Barwin is almost a clone of Paul Kruger. The two are hybrid defensive end/outside linebackers playing base 3-4 defenses. But each possesses the skill set to transition to a 4-3 end if necessary.
Barwin is also an explosive pass-rusher who is underrated and often overlooked because of a star-studded cast around him (or in Barwin's case, J.J. Watt).
The former Cincinnati Bearcat would look good in black and gold rushing off the end in nickel situations and could seemingly handle his own in base down situations.
Antoine Caldwell, C
There is a glaring hole at center for the Saints. Brian de la Puente simply doesn't cut it. And the Saints under Sean Payton have employed a next man up philosophy at the center position. It's unlikely the Saints would waste a ton of money on the position.
Caldwell also figures to be re-signed by Houston to resume his duties at guard, but with the Saints would move back to the center position he so adroitly played at Alabama.
James Casey, H-Back
James Casey is a freak athlete who Sean Payton would undoubtedly love to get his hands on. To think of the matchup problems he could cause is almost unfathomable.
He is also an apt blocker in the run game and more than adequate in pass protection. If the team decides David Thomas has had his better days, Casey could be the solution.
Brice McCain, CB
Brice McCain was a player I loved coming out of Utah. He came into the NFL in the same year that Sean Smith was a Dolphins draft pick. Though most analysts believed Smith to be the better player, I was higher on McCain.
In the pros, McCain has been an underrated player, while Smith has faced his share of criticism. McCain is an option similar to D.J. Moore to take over the nickel spot. The only difference is that he lacks the elite play-making gene of Moore.
