Well...Dirk and Gay are good offensive players but defensive holes. Gay is just subpar as a defender in general and Dirk is almost immobile at this point. I imagine that Gay would get caught up in screens constantly and that Dirk would get eaten up by Favors in the post.
MKG is tough to play because he can't shoot from outside at all, and can only shoot even midrange if left totally open. Will throw it down if he has an open lane but also not particularly good at finishing. Just is a stopper who maybe can get to the rim in transition.
But you really don't need an offensive weapon at all positions, or even necessarily at more than 3.
I have a habit of saving my summary/score sheets...I'm on PC so it's really easy to do in the moment, to archive, and access.
