Outside of Fultz, the rest are projects, it's very possible that one of the 2nd rd picks (likely a senior) could play ahead of a top pick this year.
Someone like Fox will struggle to play ahead of TLC, Bayless, McConnell, and will be fighting with NIk (and Henderson, if he returns) for PT.
Someone like Isaac may not see the floor until he spends a year in the weight room.
Embiid, Simmons, Saric, RoCo, Holmes [Jah} - no time for a rookie forward on this team barring injury
Bayless, TLC, McConnell, Nik, (Henderson) - a guard will have to have a good outside shot and show he can play defense to garner PT.
We've seen the 'one and dones' - look at guys like Dunn, would he play as a rookie here?
Ingram, Chriss got PT b/c they were on terrible teams, Dunn and Brown played 15 minutes a night.
Someone like Fox could play defense, but can't shoot, someone like Monk can shoot, but can't play defense.
So to me, just focus on "coachability," can a player accept the tough coaching to make him into a solid top 8 rotation player in 2018-19?
