Willie better contract and defensive range.
Just no.
Contract is fair, but defensive range is not even close. Nerlens has been a better player than WCS at every level on both ends of the court.
No right back.
WCS at least doesn't go for steals above the 3pt line letting guys drive past him. WCS usually goes ice technic when on a guard and let's his length bother the shot. Noel is too aggressive. Also WCS does better staying with people on switches. Noel is a better offensive player due to put backs from better rebounding and better filling lanes.
You have no idea what you're talking about.
Nerlens is one of the better PnR defenders in the NBA. He's more mobile than Cauley Stein, and just about every other big out there. Cauley Stein basically can't get on the court this year, do you know why he ices? Because that's all he can do. They played together in college, and it was as obvious then as it is now that Noel was much better.
Opponents are scoring 11 more points per 100 with WCS on the court this year, and he was a negative last year too. Nerlens Noel has been a massive positive for the Sixers both years on that front, even given that he spent a lot of last year out of position. Heck as a rookie they were a top 5 level defense when he was on the court despite having Ish Smith and Isaiah Canaan as perimeter defenders for like 1/3 of the year.
It's not even worth discussing, as a rookie Noel anchored a defense that spent most of the season in the top 10 till they lost most of their wing defense. WCS has done.... Nothing
