I'd take a flier, I mean why not?
But let's think about this, playoff rotational speaking.
PG) Kyrie - LeBron - Shump
SG) JR - Shump - Korver
SF) LeBron - Korver - RJ/Lance
PF) Love - LeBron
C) TT - Frye - Love
That is arguably the rotation of players at the positions they play. Now good thing about Lance he can ball handle better than the average guard, that could be pretty big considering we have no backup point guard, and who knows who they're targeting. But my money is on them waiting to the last second. Good chance Deron Williams is bought out.
The signing of Lance would mean RJ is out of the rotation. Are we willing? He looks old, then has a few minutes of old school RJ. Certainly can't go wrong bringing in a tall combo guard.
