Even if IT explodes he's going to be exploited on the defensive end. His size will always hinder him against the best teams. The Cavs will always have a compromised defense with him on the floor. Wade doesnt provide the spacing that Kyrie would because he's not a 3 point shooter.
I guess you could choose the wait and see approach. But what is going to change those facts?
Maybe if you're talking about health and chance...sure. Maybe the Warriors dont make it back...maybe someone's hurt.
But if we are just looking at the players based on what they bring and based on their weaknesses its easy to make an educated guess.
What about the rest of the team lmao. Kyrie isn't the world's greatest defender either. Curry is a liability too even though he gets steals. Case in point the 2016 nba finals and all of the switching they did on him forcing him to defend and we all know how that turned out.
You're worried about Wade not spacing the floor but ignore the other things he bring like his playmaking and his ability to get in the paint as well as being able to take the playmaking load off of Lebron.
Draymond shoots only 30% from 3 yet no one is concerned about the lack of spacing he brings because he is an excellent passer, decent rebounder, and elite defender. The Cavs also still have Lebron. Even though Love is ineffective against the Warriors, they now have other guys that can help take off the load. IT's size becoming a problem? Put in Rose for stretches.
Kyrie only really exploded in games 3 and 4 and was forgettable in the other games. The Cavs don't need IT to be Kyrie because they now have a much better supporting cast. Kyrie had to explode for them to have a chance because their supporting cast performed horribly in the finals. Now it is reasonable to assume the supporting cast they have now will perform much better so IT won't have to drop 40 every night for them to have a chance like Kyrie had to.
The Cavs big 3 wasn't the problem. It was the team around the big 3 yet people want to ignore that. You can't beat the Warriors if your supporting cast shyt the bed the way the Cavs did. The Cavs lost Kyrie but gained IT, Rose, Wade, Crowder, Green, and and still have guys like JR and TT even though TT has the Kardashian bug right now.
