Benning has a 50% hit rate on top 10 picks
Actually he has a 75% hit rate (most likely 100% once Juolevi plays), with a 50% home run rate. The expected return on a top 10 pick is not a home run player, contrary to what some people seem to think...
And he got Boeser at 23, and other non-trivial hits in the later rounds like Demko, Tryamkin, Gaudette, Forsling, and an another amateur find in Stetcher. Other guys likely to come. I get it's not perfect, but man you could do a lot worse with some of these other "smart" GMs.
Let the guy do what he's good at, and then if you don't think he can handle converting a pool of amazing young players into a playoff contender then find somebody to do that at that time. We're not there yet.
