Good for Pierce for speaking up. He really made a strong and specific case to give the young guys a chance and him some rest. Doc of course has claimed he's going to do this, as others have noted, for weeks now. But along with not actually doing so, Doc after the last game talked more about having his short veterans fill in against the tall wings into the future.
Thankfully Pierce spoke up yet again. And, did you notice, he did so at the same time he gushed about how he'd want to retire rather than play for another coach after Doc. You'd almost think he's been reading management books and decided to use the 'sandwich technique' of praise, correct, and praise again. Of course that approach has been debunked as too obviously manipulative if used regularly, so let's hope he got through to Doc this time around!
