It's been my opinion for awhile that Noel is overvalued as a trade piece. Is he better than Hassan Whiteside? Do you want to pay him $25 million in 2017? If you don't, do you think someone else will want to?
At the same time, Philly needs a PG who knows how to run an offense. They need someone who can get the ball to Okafor and Embiid in positions that will allow them to score, and not 10-15 feet from the basket in a face-up situation. With two interior players, or three with Simmons, they need that PG to be a threat shooting the ball from deep to keep some amount of spacing on offense.
If Teague walks in a year, it'd be a bad deal. But what if Team Colangelo is able to convince Jeff Teague to buy into the Sixers, and extends him this summer? Now you've got the very good PG you need, who can make sure your young guys develop properly, being given the ball in situations they can handle, as opposed to developing bad habits because they never get the ball where they need to, and because winning is never a goal.
And if Okafor or Simmons or Embiid take a quick step towards stardom, now you've got a veteran like Teague there to help recruit a free agent next summer. And since Hinkie did a nice job of getting a pick swap with Sacramento next season, they can try to start winning now, and potentially still wind up at the top of the lottery. That team's goal should be to win 30 games this year. They don't need to be special, but they do need to stop being the laughingstock.
