They remind me of the Thunder before they broke out. Although Giannis and Jabari aren't at Durant and Westbrook's levels, and they don't have a Harden type of third banana. A healthy Middleton, while good, isn't Harden. What they have is the eastern conference, which is a great asset.
Giannis is gonna be the future best wing player in the NBA, although with so many quality big men coming up in the league I think we're gonna go back to the 80's where you have all these dominant PFs and Cs but the franchise wings aren't as plentiful. The likes of Beal etc. can't hold a candle to the crop of big men including KaT, Porzingis, Drummond, Capela, Gobert etc. Anyway regarding Parker I guess he kind of got rated below Wiggins because he was a PF in college and people were thinking he might suck as a PF because he's bad defensively and his crafty moves might not pan out as much in the NBA, oth Wiggins has the prototypical swing man body and already has an NBA level talent with his defense. But it's been around 3 years since they were both drafted, just like Melo and Lebron over time the dude who has a great work ethic will start to separate himself over the dude who does just enough work to get in shape. I think Parker is way better as a power SF like Artest/Melo/Pierce rather than playing PF as you can minimize his bad D on the perimeter and he's managed to get a working J.
