See this post is really confusing. Eubanks is a project? He’s a career backup and a pretty decent one at that.
I think you overestimate other teams size for one and for two, never talk about matchups because posts like this seem to be against the idea that teams should match up to us not the other way around, which Monty liked to do.
The NBA is a complex league, far more complex that dumbing it down to big vs small. You’re also making Middleton out to be a big man when he was only an inch or two taller than both Bridges and book. Now our power forward is 6’11” KD and we suddenly don’t have size to match up with the Bucks today? Huh?
Where did I say anything about Middleton? Seems you're mixing two posts together. Regardless, Milwaukee were playing Middleton at SG, which gave them a real size advantage. Our PF now being bigger than him should be expected since he was their SG. They were able to play big with 3 7' footers on the floor at once in Lopez, Portis, and Giannis with 2 big guards in Middleton and Holiday in the backcourt. We couldn't matchup then and would have trouble now, anyone would. Our length would help mitigate some of their size advantage but some of our long players like Bol and Okogie aren't guys you'd want to play for long stretches in a championship series.
KD may be 6'11" but can he guard Giannis, Brook Lopez, or Bobby Portis? He's a PF because of what the NBA has become for the most part, taller SF's stretching the floor and covering PF rather than PF's being smaller Centers. He's not going to be guarding most bigger PF's in the league like Anthony Davis or Giannis, which is fine so long as he's efficient enough to force matchup problems that keep teams from going big against us.
Monty tried forcing Milwaukee to match us but it didn't work. You can't always force matchups you want. That's coaching 101. If you don't think Vogel is going to do similar stuff then I don't know what to tell ya. Sometimes though you need to adjust and match your opponent and I don't think we're equipped to handle playing a larger team. That's fine because there aren't many but if we do face them in the playoffs or Ayton isn't able to be counted on, we'll be in trouble.
Eubanks is now a career backup? That's news to me, probably him too. He's been in the league 5 years and did nothing of note until last year on a bad Portland team. He was on two-way deals and was essentially San Antonio's Ish Wainwright until he was included in a Thad Young trade, after which he waived. Then signed another Two-Way in Portland. Last year was his first year without traveling back and forth to the G-League on a bad Portland team. 1 year as backup doesn't make him a career backup. He's had 1 semi-notable year as a backup, which was last year. It's too soon to say he's a career backup given he looked up a fringe NBA player his first 4 years.
