No, I'm not calling Agau, Fore, or King "contributors". But I'm also not labeling the Top 8 by playing time with that.
The major contributors on this team IMO are Cunningham, Nwora, Enoch, Sutton, and Williams. I'd put Fore, Perry, McMahon, and King down as logging minutes but hardly indispensable. Again IMO, we're losing 3 of the first group (of 5) for sure, and 50-50 on Williams. If I want to roll Sutton's odds in there, it's a high probability (90+%) that we lose 4 of those 5. That's why I say "most" will be gone.
Not saying you're in this group, but hometown fans consistently lowball the odds of losing players early to the pros. You'll actually hear people argue that Nwora will return which is crazy. Or Enoch who is now four years out of high school. Those two are history along with Cunningham who is extremely valuable to this team.
And I'm similarly pessimistic on the immediate contributions of the incoming freshmen despite Mack's coaching abilities. I like the quality of these guys, but they're not ranked high enough to be immediately successful based on talent alone. That's what OAD kids do, which these guys are NOT...
