Chemistry is an interesting point to raise, and definitely one that is worth consideration. It's why I am so against the potential addition of someone like Marcus Morris or Jae Crowder. Guys who have previously been issues in the locker-room, and who believe they deserve more of a share of the ball than they would get here. They also don't really fill a need, in my opinion.
The only issue I have with our roster construction is, assuming Ime perseveres with the dual-big starting lineup, we do not really have a backup 5 unless we have Grant or Gallo play there. I don't think either is ideal as the 2nd string centre (fine as 3rd string in small ball lineups). However, if we start Brogdon/White, then that is solved by Al/Rob going to the bench.
Like this past season, Al or Rob will constantly be on the floor as the #1 and backup Center. I’d like to have a 3rd Center to play 4-8 minutes or as an injury replacement. I’m also prepared to see Gallo and Grant as the 3rd and 4th string Centers if it comes to that.
Chemistry and injury issues can derail a potential Championship team. We saw it happen to the 2018-19 Celtics team and can point out similar situations in underachieving preseason favorites. A disgruntled idiot feeling he deserves more minutes than he’s getting can implode a team by recruiting others in their dumb crusade.
Disgruntled idiot: “I deserve more minutes, you deserve more minutes, we all deserve more minutes! Who’s with me!?” In a separate conversation, he whispers to a teammate: “How is that guy getting more minutes than you? They’re trying to keep your numbers down to re-sign you for cheap.”
Which is why the main goal of the individual player has to be to do whatever they’re asked to win a Championship, not get force fed minutes to accumulate stats for the next contract. Everybody has to be on the same page.
