I've been saying this for awhile, but I'd bet Deron gets stretched or bought out. I think he'd be a steal at the mid level exception. He's still a very good player that has a family who lives here. Bring him back. He'd fit in well in Snyder's system.
I'll proclaim this plan until it doesn't happen:
Trade Burke, Booker and #12 to GS for Lee, Barnes and a future pick. Sign Deron to the mid level exception.
Exum/Deron/Cotton
Hayward/Burks/Millsap
Barnes/Hood/Ingles
Favors/Lee/Barnes
Gobert/Favors/another big body
That team wins 55+ next year. Length, shooting, athleticism, depth. That's a great team.
