I certainly agree with Pryor, but then again I am a bit higher on him than most. I actually feel that Myron Pryor is pretty close to being a lock, as long as he is healthy of course.
Brace to me is still somewhat of a question mark of sorts, and sometimes it's hard to get a good read on certain situations. I will agree that it is certainly a valid point that his competition is lessened this year, although that could/should change somewhat with the probable addition of at least 1-2 players on the DL prior to the end of the summer (just a gut feeling due to the lack of enough bodies and competition, but I obviously could be wrong). One could also make the argument that the placement of him on PUP last year may have helped with that competition, then again I suppose that one could also make the argument that his being injured in the first place may have hurt him a bit--so it's probably a wash. I'm going to assume that they wanted to continue to allow him to progress another year, and that is the point that may be pushing me to wonder if this could be his last TC. This will be the 4th yr here if he makes the roster, and I don't know if we've seen enough to warrant that spot. As you say, current lack of DL competition is certainly favoring him at this point.
I think that this is a very important TC for Ron Brace personally, but it should certainly be noted that he has looked impressive at times in run support when healthy, so there is a strong possibility that he may have not fully reached his potential due to injuries etc.
I think he is one of the more controversial players on defense, along with Cunningham (who I see making the team, unless M.Carter really shows us something). Both will be worth keeping a close eye on during the month of August. As I said, I am certainly pulling for Brace to make the team.
