More Dieng = more rim protection.
as for lack of a go to scorer in the 4th, they lost every close game they had, and that was WITH Love (and that's due to a bunch of different reasons besides scoring-- coaching, Barea, Barea, Barea, coaching, defense, Barea. How could it get worse in that department?
I'll ask you this. Did you watch the T'Wolves play without Kevin Love and think "damn had he been out there they woulda won tonight?"
By willingly losing games, you'd be answering that question for them. And even if you're adding more talented rookies (which is not a guarantee), all you'd be doing is teaching them how to lose, and when do you plan on breaking that cycle?
