To put it out there, I think the depth of this draft is far worse than last year. More star level talent among the top 5 guys but I don't see a franchise changer.
I'm not sold on Bagley or Ayton offensively as high usage bigs and both have pretty ugly defensive projections. These guys aren't AD, Cousins, Towns, Embiid level prospects. Plenty enough natural talent to be all star level players, but I don't think that's a safe bet and are ultimately tough to build winning teams around.
Trae Young and Luka Doncic look like they have a chance to be primary offensive weapons, but both have legitimate physical tools concerns.
Porter Jr is the wild card with the back injury and no college tape. The HS and world stuff I've seen of him though has left me unimpressed. I get the size, shooting and athleticism combination, but he's always seemed stiff and awkward to me in some ways and a little lacking in the IQ department. Doesn't have many advanced scoring moves either.
Jaren Jackson Jr and Mikal Bridges are the two good bets to be pieces on contender type teams as elite defensive players and efficient support pieces offensively. If Boston ends up in the Top 3 again, I would not be surprised to see them trade down with a team looking for a potential primary offensive weapon and taking Jackson Jr. and picking up another future lottery pick. He'd be a great fit there.
Bamba could belong in this group too, but I'm still not sure if he'll ever be good enough offensively or versatile enough defensively to be a 30+ minute a game type player on a team with contender aspirations. He's also the one top guy I've seen the least of so far though.
Wendell Carter Jr. is pretty underrated. He might have the most balanced skill set of all the bigs, but he probably doesn't have the skill level or tools to be elite on either end. Think Derrick Favors with more shooting.
I'm lowish on Miles Bridges and Colin Sexton. Sexton seems destined for the Suns and I'm just not sure what to do with Bridges. He probably has enough athleticism, strength, shooting and playmaking to be a useful two-way combo forward and honestly may be the best fit for us if we found ourselves in the lottery, followed by Mikal Bridges. Good fit as a connecting piece between Collins and Nurkic.
