On the Celtics' Blount and Banks

I wrote this on 8/4 (Link) in a thread about the rumor that the Celtics' Blount and Banks were available as a package for expiring contracts
Blount retired on the job after getting his big contract and got 3 DNP-CD's in the Celtics' seven game playoff series. His contract runs for 5 more years. He has got a 15% trade kicker in his contract that would raise his salary for this year to $6.325 mil and his salary in 2009/10 to $9.16 mil.

Banks is a short SG who is a defensive marvel, quick as can be, can't shoot well and who happens to get time at the PG position. He played fewer minutes last year than he did his rookie year. Unless his game improves dramatically, he is at best a back up PG and more likely out of the league in a few years.

Why, oh why, would the Lakers be willing to give up their dream of getting a big name FA in 2007 for these guys?

Someone challenged my assertion that Banks is likely out of the league in the few years, so I added:
Statistically, Banks and Tierre Brown are extremely close:
Tierre
14.03 mpg, 4.38 ppg, 2.04 apg, 0.97 to, 2.10 A-to-T, .356 FG, .361 3pt

Banks
14.14 mpg, 4.59 ppg, 1.91 apg, 0.98 to, 1.95 A-to-T, .402 FG, .356 3pt

Banks is a much better defender, but I can't see anyone who puts numbers up like Tierre's sticking around long.
