With Quinn sidelined until at least mid-Sept, he may not be back in game shape by the Blue-White game.
That would leave Duke with only 4 gfuys to share the PG/SG slots Seth, Austin, Dre and Tyler.
So they will likely be split up somehow rather than going with Seth-Austin-Dre- Ryan- Mason starting 5 versus the rest. With Quinn, that would have been possible.
Then Alex Murphy and Mike Gbinije pair off, Ryan and Josh/Miles and Mason vs. Miles/Marshall.
The alternative would be Thornton - Gbinije, Murphy, Hairston and Miles.
So with Todd Z, Duke is very deep among the bigs.
Get well soon Quinn, but don't rush it this time.
