He played LT exclusively for 5 years before the last 6 games at RT. I'd flop him to the left side in a heartbeat. You can't help Tucker and Petitti, and if we flop them, you could still help on Rob's man, and leave Tucker more or less on his own. Don't forget the left side is Bledsoe's blind side. What would you rather have, Tucker over there on his own most of the time, or Rob over there with help? Also, I think the run blocking might actually be a little better with Tucker and Rivera on the right.
Also, Flozell is 30. Not all that old for an OL, but when he comes back next year, he may want to finish his career on the right side anyway. He's certainly not going to be any faster at picking up those edge rushers coming back from a knee injury next year.
