Since I am no longer on the road and can type more, some more thoughts on Simons and Bonga.
Anfernee Simons
Positives: He reminds me a lot of Markelle Fultz or James Harden, that same sort of herky jerky motion that puts defenders on their heels and allows him to get shots off the dribble that he has no right getting given the athleticism. The shooting form is good and he finishes effectively now (more on that in a moment). He's more of a new fangled lead guard than an old fashioned point guard, but his height and length could serve him well in that role. He's a willing defender, anticipates passing lanes well.
Negatives: He might be 170 wearing a flak jacket. He needs serious time in the weight room to bulk up if he has any prayer of finishing at the rim in the NBA. His willowy frame is also going to limit him on the defensive end, and because he's basically a college freshman playing high schoolers, there's a question of how well the whole package holds up against grown men.
Overall: He clearly needs to add another 35-45 pounds to his frame, and there's no way of projecting how this impacts his game at the moment. It's why he's all over the place on 2018 mocks. He likely spends the first couple of years in the G League, but Boston is in the position of not needing immediate contributions from their draftee, so they have the time to let him mature in Portland.
Isaac Bonga
Positives: Tall and long. 6'9" with a seven foot wingspan. Quick and athletic enough to handle Boston's switchy defensive scheme. Dribbles really well for someone that size, a crack whore's Greek Freak. Great shot creator, especially for others.
Negatives: A crack whore's Greek Freak. Not much of a shooter. He's not Simmonsesque, but he's also not the athlete that Simmons is, so he can't get where he wants at will. He is passable out into the 14'-16' range, but he doesn't shoot many threes and shoots them at a Marcus Smartian rate. Like Smart his FT% is so good that you would assume that he'd figure out the distance shooting, but that hasn't worked out for Smart, so there's a real question there.
Overall: If he puts the tools together he's a real asset. Otherwise a JAG. He tends to be in the 25-40 range on most mocks. He offers Boston the same advantage that Yabu Dabu Du did, he can be drafted and stashed overseas for a year leaving Boston with the luxury tax space to roll this team back next season and make a real run at the title.
