No thanks.
Al Horford is one of the best Bigs in the game today - not a "Great Player" in any one statistical category BUT a VERY GOOD player in MANY...
Plus, he's a great teammate and seems to be a great locker room presence.
He's never been a great athlete BUT with his vast skillset he'll be VERY effective for us for the next 5-6 years.
Keep him and this core we have and simply add a piece or two to it.
