Not that Jacquez is close to the level of Dejounte Murray, but it kind of reminds me of when he was suspended for Game 5 last year and we thought it'd make things way easier. Then we blew Game 5 and had to go to a 6th game vs. Atlanta of all teams. That also felt like the first sign among others that last year's group might not have what it takes to make the Finals.
So yeah, while tomorrow isn't a traditional "must win" it really is one they shouldn't lose. If they do, I think that's not a good sign. Even without Porzingis they need to take care of business at home and get rid of these dirty Heat. You also don't want to give the Heat an extra 48-96 minutes to possibly injure more of our guys if you lose Game 5.
