Mike Dechaine argue's more about racking than anyone else is basically due to the fact that he reads the rack better than everyone else, maybe he competes with reading the rack good with Corey Deuel, but maybe Corey sometimes let the opponent go with whatever theyre doing, but Mike is not scared to call on anyone.
Now don't get me wrong, i'm not saying that Morris is doing anything because I haven't watched the stream or match, but all I'm saying is, Mike reads the rack really well so sometimes he picks on things more than anyone else, then he calls the opponent if he believes something fishy is going on.
So maybe thats it? this explains why he argues alot about racking.
But in the end lets be honest, the break shot and racking has been a problem in the pool game forever, and this will never change unless the pool world implement a new way of either racking or breaking, and please magic rack lovers, don't tell me magic rack is helpful or fixes it, magic rack destroyed the game further.
