There are a few things I respect about the MCW move. They bought low and probably sold high. MCW may have a ROY, but his limitations might mean he settles in at a middling type guard. He is nothing transcendent.
Also, I respect the decisiveness. They might have decided that MCW either wasn't their guy or they might have decided that MCW was really unhappy with the environment. I don't know why they gave up on him, but I respect an organization that isn't afraid to do moves like this if they think it is the right thing.
It does seem like a game of kick the can, but you can't be afraid to make adjustments that you think are needed.
