I wonder if he might get some play this week against the first team. He was in starting with the second drive last week and looked pretty good. He played about a half, I watched him on every snap last night. He really just had a couple of poor plays, one on a batted down ball where his guy didn't bat the ball but was a serious part of the pressure on Cassel. And then on a blitz he helped double an inside guy while letting the outside guy rush free - I assume this wasn't the correct decision. Other than those two plays, though, he took his guy out on the pass rush nicely, got some good push on the run blocking and even got to the second level a couple of times on run blocks. With Kaczur's disappearing act so far, I would love to see O'Callaghan get serious reps with the first team as the possible starter at RT.
