Honestly, I'd have to wait to see how things shake out. Who knows, Ainge might already have Bradley ready to go in a deal. I wanted Portis, but liked Rozier before the draft, (pat on the back for mentioning him as one of the few players I liked BEFORE the pick), but getting Mickey kind of minimizes the need for Portis.
If we land a big in free agency, or get a wing like Harris, then this draft looks totally different. If you draft a big early, I think it kind of says you aren't in the market for a big. Maybe Ainge already knows he didn't need a versatile scoring big in the draft so Portis didn't make sense.
