If --- and that's a huge if --- Pierce wanted to go to the Clippers, we would very likely do a S&T; the Clippers are notoriously cheap and aren't gonna pay more than they have to, esp. with a potential lockout.
I wan't Pierce to retire a Celtic (and for the C's to reload, not blow up tthis summer), but it we got Eric Gordon and a future Clippers #1 for him (and the cap room left by Pierce) that's an OK plan C
