I tend to agree. Lauri really thrives playing off the primary action. Lauri and Collins share a lot of similarities (in a good way), but Collins is more tilted towards being around the basket whereas Lauri is more perimeter oriented. I think it works and would love to see what Hardy does by adding an elite rim runner. Even playing in a less than ideal role, Collins has been pretty damn good regardless. Last three seasons he's a 21% usage player at 62 TS%, not bad for someone getting phased out of their greatest strengths. Playing with Lauri is infinitely better for Collins than Capela, and I think Collins also benefits Lauri on offense as well. I don't even think you need to give Collins more shots to keep him happy, you've just got to include him in more actions.
Defensively, I think there's more uncertainty. Like Lauri, I think Collins is/was underrated on defense. I really liked what I saw from Collins in ATL's long playoff run. He's tougher than people give him credit for, and he has all the physical tools. I think both guys are versatile and pretty good in most situations, but at the same time you probably don't want either of them to be your primary rim protector or on ball defender. So while they aren't weak links, you probably need to fill out the rest of the lineup with at least one elite defender.
