I just can't see it - Larry and Vogel probably wish that Simon had not talked publicly about the possibility of Lance returning to Indy.
Lance has had a couple very nice seasons (and post-seasons) lately, but it seems like all they need is a capable PG (not too difficult in today's NBA) and they should be okay once George comes back. I would find it crazy if Indy brought back Lance - a) they could have kept him on a reasonable contract, but chose not to (and now he is performing much worse), and b) the players (ie Hibbert) on the team may not welcome him back with open arms.
