I don't know if they need to tank. I do, however, think they need to make a bold move in the off season.
I'll get negative Tommy-points for what I'm about to say, but I would trade Paul and the first-round pick for some established youth on draft night. Personally, I think the Sixers would be a perfect trade partner even though they are in the same division. They need cash savings, and the Princeton offense is all wrong for the type of players they have (everyone but Brand that is). If I were Danny I would see how open they were to trading Paul, Perk, and the first for Iggy, Dalembert, and Young. Gives the C's much needed youth and athleticism while staying competitive. The Sixers get to push reset while getting back talented players to complement Brand.
RR, NR (Re-signed), Vet minimum player
RA (re-signed), MD (re-signed w/MLE)
AI, TY, ML
KG, GD, SW (re-signed)
SD, RW, 2nd pick
Regardless of what they do, I'd really like to see the team transition into a younger, athletic running team built around Rondo.
