All reports made it sound like Irving is as good as he's gonna get right now, and just has to learn to play through pain in the knee. That is why they wanted him to go in game 4. He's never played through injury before and just has to get used to it.
But James was really getting weighed down. Having Irving around to help create on offense really freed James up to do more on defense in game 4. I think tired legs is a big reason why his 3pt shooting has never come around. If he could get his 3pt shooting up to his season average (35%) it could be a series changer. I can't believe he's looked as good as he has while hitting only 18% of his 3s. Kyrie is making 48% of 3s in the playoffs (nearly 5 att/gm), Smith is 40%, Shumpert and Delly are at 36. Put LeBron at 35 at Cle might just pull it off.
