I would have put Robert Williams in with 0.5 secs left. He is our best shot blocker and intimidator; Toronto "feels" his presence. No risk of a pump fake foul at 0.5 sec.
Do I think it would have made any difference here? Probably not. But the Tacko think was kind of ridiculous IMO. The refs were having him stand back, which defeated the purpose of imposing his length. Plus we have seen Williams on more than one occasion deflect an inbound pass. If he rather than Brown were the one recovering toward OG, he probably would have blocked it.
Keith Smith points out that the real culprit was probably Theis, who went beyond his zone coverage, which forced Brown to stick with Gasol. Had that been Time Lord, all the "fans" who claim he doesn't play good system defense (as if they even understand Celtic defensive system well enough to criticize (they don't)) would have been jumping down Rob's throat.
Brad needs to wake up and play RW3 more minutes, including game ending moments.
