People on this board thought he was cooked going into last season, and he had a very solid year as a starter for the Spurs. Taking him on to be something between our 9th and 11th man isn't a stretch.
I disagree, I thought Finley was abysmal last season and one of the main reasons San Antonio struggled. His inability to be a solid role player, along with a couple of other role players, destroyed that Spurs team. They were never good enough to compete for a title because of players like Finley. Even with a healthy Manu Ginobili.
Not that was Finley's fault. It was San Antonio's for asking fill a larger role for the team than he was capable of filling. In the correct role, a fifth or sixth wing, he is still a competent player.
If we acquired him, I'm fairly confident Doc would eventually slot him in as the 4th wing, bumping TA out of the rotation for all but the most difficult match-ups on D.
The lack of shooting/spacing off the bench clearly gives Doc fits. I've seen how frustrated he looks when the ball-swing yields wide-open jumpers for Rondo, TA and Daniels. I believe that's one reason why Doc is tolerant of Sheed's 3's: it's the only shot at spreading the floor and killing the traps teams throw at our guards off the pick and roll.
And Finley's lack of rebounding isn't likely to ruffle many feathers. Just look at Ray, Paul, Marquis and Sheed's positional rebounding rates: the rebounding bar has been set pretty low.
