Lots of posts on this one! Moore is a good pickup even if Smith does come available. If I can remember all I read on this one:
Moore is a hard playing backup, not a project like Obryant (soft?) or soft with a bad attitude like blount

He can hit the outside shot and to me the most important this is as a long big he is athletic enough to cover Toms rotations. Mutumbo, I love but no way could he have come to the c's and helped on our defensive rotations. Gotta be athletic with good foot speed (and be younger than 50!)
We have signed Moore to a nice contract, he's young enough that we can get more than a 1/2 season from him if we want. PJ did a great job, great career, true professional. He wasn't perfect (which moore & smith wouldn't be either).
If Moore brings the energy that I'm used to seeing from him with his length and can hit the outside shot its a GREAT signing. If he boxes out his own man then I don't care if he averages 3 rbs a game.
Can Moore give us 15 minutes a game and help? yes
Come playoff time..can he guard opposing bigs for a bit (z) , give us some fouls off the bench and hit the outside shot. i hope so

I liken his signing to what we need in help for a series win, z is too tall for baby/powe combo. If he does a good job against z then i'll be happy.
Also final thought..who will he be on the floor with for a pf? Powe's low post game goes nicely with moore's jumper huh?
