I don't see him clearing waivers someone would sign him, is it like baseball?
If he's waived then a team would need enough cap space to absorb his entire contract I believe.
I can't see a team spending that much cap space for a single year of Pierce.
Not sure how the cap works or much he'd want to leave on the table but something tells me Pierce would waive and re-sign to a friendlier contract to reload for one more run
It wouldn't really help them, because it wouldn't create any cap space. So, its not going to happen.
Plus, I think Pierce wants to win. If the C's waive him, he will go chase a ring.
By far the most likely scenarios though, are they trade him, or they keep him.
