I like TA a bit better for his great defense, physicality and rebounding, but Brewer is a lot better option than most.
Like Daniels, Rondo and TA he's crap from 3, but unlike them, he's half-decent from mid-range. He can even handle the ball a bit and make some solid passes.
Defense is a few levels below TA's (Kobe, for one, has given Brewer all sorts of problems 1-on-1) but still pretty good and he's an excellent transition weapon.
All told, he's like a more athletic Marquis Daniels.
