Manu I think it's a fair call that they're better, but I don't know if the margin is as big as you think. Stevens is unbelievable at both scheming and getting buy-in, and Irving was a vastly improved defender in Boston than prior. We didn't get to see what Hayward looked like in Stevens' system, but he's been part of a league-best defence in Utah and while Gobert is the core of that, Hayward isn't a sieve. I think there are more minutes going to guys who are better defenders as a result of those two injuries, but the most straightforward replacements - Rozier for Irving and Tatum for Hayward - aren't clear-cut defensive upgrades.
