Well that's what I was thinking in early Janurary. I first thought about it after a game against the Rockets.
I just wanted to start him to see what happens. I really thought at the time with the Spurs struggling offensively that Ime could start and we might get more production out of him if he's getting open looks from Tim. I wanted Michael to be the one that went to the bench though, not Bruce. Ruff, I think was the one that also suggested that it could be for Bruce since Bruce was in a funk at the time. I think that is the only reason Ruff suggested it actually.
Now if we were to do it that way I'd bring in Bruce at about the 6 minute mark of the first quarter, no later than that though. My thinking is after Ime has played his brand of tough physical defense Bruce can come in fresh as a daisy and play his suffocating defense on an already slightly tired starter. I still think it could work if Pop thinks a shakeup is needed.
