Much rather have Duval than Knox. Duval is a must get for next year to be a good year for the team. Even with him, Duke's probably only a top 15-20 team (assuming the exodus happens).
Interestingly, Knox went 1 for 10 from 3 in his most recent HS playoff game loss. 8 for 23 overall.
Duval fills a critical need. With Duval, you have a kid who will run the show, and you can throw in Frank as a combo guard and Trent, Jr. will be a solid scorer, slasher. Then feeding the big guy, Carter, and that's a really nice set up. Add Javin into the mix and he'll get a few buckets.
But, if there's the exodus everyone is talking about, then Duke is going to be pretty thin next year. We def need Duval.
One thing will be interesting if we are think next year is what kind of minutes Vrank and White will get. I'd like to see them get some time. K, of course, seems to be all or nothing on time.
