Pass on that trade, not without other assets. Might consider Calderon plus Amir Johnson for Jefferson, but even that would be a stretch. Never trade big for small.
One I would almost definitely do is Lowry + Amir Johnson for Millsap + Tinsley/Watson. Toronto gets cap flexibility and a good opportunity to sign Millsap long-term. Utah gets a solid back-up PF so Favors can start and a starting-caliber PG who can fill-in for Mo Williams or takeover long term, on a reasonable contract.
