So basically, another of your novellas that says nothing.
You said tangible things, I gave them to you. It's not "nothing" -- it's just things that you apparently think don't matter.
If you meant to ask, "Has Garrett won more games than Wade" then maybe you should have done that. The answer is obviously no.
However, I think all those things that he is doing differently than Wade are definitely getting more out of this team than Wade would have been, as evidenced by Wade's approach resulting in a 1-7 collapse.
Though obviously the question of whether Garrett should stay and whether he's better than Wade are two separate things.
