Game 2 saw Tatum have the most drives into the paint in a single game across his 623-game career. Brown had the 2nd most drives into the paint out of his 661 career games played. That led to a lot of clanked layups or kick outs for wide open spot up threes that the Celtics just didn't make (IIRC, 34 of them). Anyone remotely thinking the Mavs defense is fine and not a major issue is not paying attention. Boston players are getting by Luka without much effort (and many times without screens). On top of that, the Mavs defensively have been trying to hide Kyrie on the back line under the basket (which also hasn't worked . . . Holiday was scoring at will from a foot from the basket). I would not be surprised if Tatum went for 35+, Boston hit 20+ threes, and with a lot more shots falling, that Boston will score into the 130s in Game 3.
As far as KP goes, he was seen entering practice this afternoon dressed to practice without any sort of brace on, no limp, no change is his gait, no anything. Shams echoed what I mentioned earlier . . . that they will check him again in pre-game warmups with the hope that he will play.
Edit to add: another thing I forgot to mention, the media's narrative was Boston won three playoff series at full health (not even mentioning KP being out) playing against opponents with key injuries. No one even mentioned Porzingis when he was out. Now we get to the Finals, and suddenly KP is the most important player for Boston in the series . . . and some people have wondered if Boston could still win without him. OK, media talking heads, hoops analysts, and so-called experts . . . which is it? How was he mostly irrelevant for over a month, but suddenly the world would be knocked off its access should the C's not have him (and his 20-22 minutes a game)?
Also, it has since come out that Porzingis participated in afternoon practice, FWIW.
