Honestly if I were a Cavs fan I'd be a little bit pissed, because the best two scenarios for them would have either been:
1) Get Otto Porter this year
or
2) Land the #1 pick next year and get Wiggins
However, while I don't think Noel will be a huge impact player, he's just good enough, along with the progression of guys like Waiters, Irving, Zeller, Thompson, etc, that there's basically no chance they get the #1 pick next year so they'll be missing out on the two best SF prospects this year and next. Now, I take it back if they somehow do land the top pick next year, because Irving, Waiters, Wiggins, Thompson/Zeller, Noel has the potential to be one hell of a lineup, but the odds of that are slim to none unless Stern decides to rig things again.
