I don't see us buying the 18 pick. I haven't heard any rumors of teams in the top 10 wanting to move down for multiple picks. Maybe there is one, but if KP knew their was one, he probably would have bought this pick already or traded for it.
IIRC, they had to pick up his option for 2010-11 by Oct 31, 2009 for him not to be UFA this summer. (THey did). If they don't pick up his 4th-year option (2011-12) by Oct 31 2010, they can't make him an RFA.
