Most of the mock drafts I've seen have the T-Wolves taking a SG/SF like Harden or DeRozen. Now, if the concern is about entourage..DeRozen's is probably far worse. That kid was brokered as a commodity from about 15 years on. His brothers actually got into a fist fight over his choice of AAU team.
If the T-Wolves do draft Harden I think it's a huge mistake. Not because Harden can't be a good pro but because they could have kept Mayo, probably ended up with a similar record, and then plugged in this season via draft a better complimentary frontline piece to Jefferson like Thabeet or Jordan Hill. You won't get the rebounding that you'd get with Kevin Love but you'd get better and more athletic defenders with (especially in the case of Jordan Hill) tremendous offensive potential.
