The OP's ability to latch onto one fact or stat and hold onto it like a putbull while regurgitating said fact while also regurgitating his view point of view based on that fact/stat without taking anything else into consideration is.....admirable. I guess.
I think its also wrong. Tons of things lead to the loss in game 6. Rebounding...yes. But horrid shooting, lack of ball movement, lack of transition defense, lack of effort to 50/50 balls, lack of anything off the bench resembling offense other than Morris, bad defense on Giannis and Middleton.
There are a bunch of reason we lost. Not sure rebounding is the most important reason but it contributed. I have no problem going from Ojeleye to Baynes in the starting lineup. I think I like Horford on Giannis better than Ojeleye and Baynes can give you some offense, Semi can't.
