I count 52 also.
About the OL. I don't know if it's wise to count on Dixon, Cesario to backup Smith (your projected LT). If they decide to move Dixon in camp, then it's ok. You'll have Brent Smith backing up both spots. But the decision has to be early in camp. Because if Smith stays at LT and gets hurt or falters, the only other OTs on your roster are Wade and Cesario. And neither man can handle the left side. Hell, neither man has even WORKED on the left side.
The only other man (besides Dixon) who's ever been out there was Jamie Nails. And that is in college. He's been converted to guard. So that's something the board can debate.
So much will be at stake during the Titan and Bucs practices. Especially the Titans. Because that's when the decision will be made.
