Parker looked good against the Cavs three nights ago, but he looked fatigued against the Suns last night. The stats make it appear like he had a decent game with 11 points and 11 rebounds, but there were multiple occasions when he was too slow on defense. Since he is Mormon, it couldn't have been him being exhausted from having a late night out in Vegas. The real problem is his conditioning.
With that said, the Bucks need to get a trainer just for Jabari. They should be attached at the hip so Jabari is constantly working out and getting fitter. Otherwise, he's going to hit that rookie wall earlier than most of his peers.
Giannis, on the other hand, has shown incredible improvement so far. He exudes confidence and has been a lot more aggressive than he was last year. With a weak East and him being such a likable guy, he just might break the East All-Star team within the next two seasons.
