Yeah man. After Bron held up the break, Bosh just stood in the corner considerably out of bounds, looking very disinterested and careless
I wonder if Bosh tired of being the 3rd leg?
I think you're reading too much into it with the last part. Bosh probably wanted the ball for the easy score but the smart thing to do was to hold the ball and eat the clock, which LeBron did. Bosh had a few nice plays on the defensive end tonight but he's been in a slump offensively the last 3 games missing wide open J's. If anything that's where his frustration may be.
