If it is feasible at all, Loomis will make it happen under the cap. If there is one thing that Loomis does very very well, operating under the cap.
LT might be past his prime but the Saints don't need LT in his prime. The Saints need someone to play the role of Deuce-2006 where the Saints had two RB's that created mismatches all over the field.
I didn't like the idea at first because I thought all efforts should be on defense. Some moves have been made on D... resign Vilma, sign Greer. but I think the biggest impact on D will be getting everyone back & healthy in players like McKinzie, Porter, Fujita, Thomas,....
