lol still dont kno how we traded 3 end of da bench guys for a player of Courtney Lee's caliber but i'll take it great offseason foreal

Indeed!

Aside from Moore, neither one of those end of bench guys would actually produce anything for us...giving JJ, Williams and Pavlovic up for nothing wouldn't even concern me, purely for the sake of freeing up roster spots.
Moore is a potentially productive player, but even though I like him he dosn't really give us what we need. We already have undersized 2 guards in Bradley and Terry - we really needed a SG with size (6'5" - 6'7") that can play tough defense against larger guards. Moore (at 6'4") is a reasonable defender, but he's going to be a liability trying to defend somebody like Paul George, James Harden, Ginobilli, Kobe or even Wade.
Basically if you look at our guard position right now we have our pure distributer (Rondo), our lock down defender (Bradley), our high volume scorer (Terry). Lee gives us an extra scorer off the benc, a versatile insurance policy to cover (directly or indirectly) three positions on the court, and the size to defend bigger guards.
Not a huge pickup in terms of who he is, but when you can fill 2-3 holes on your team for the cost of $5M and a single roster space, that's great value. Huge deal for us
