Best HS bat in the draft, and most experts feel one of the best HS bats in a very long time. Green has by far superior tools, and will be an elite outfielder, but Johnson is the better hitter with much better contact ability. I love the idea.... I'm not sure he'd go much under slot, though...
I reject the idea that MD isn't an easy top 20 gig in the country. Maybe a little luster is off because of leaving the ACC (worst decision ever), but you're talking about a large fanbase for college basketball; top-notch facilities; a long and storied history; a campus in a large and attractive urban market; and you're the home town team, and really only major player, in probably a top 5 area for amateur talent in the country.
There's no reason that MD shouldn't consistently be in the Sweet 16 and a coach/AD who can't produce those results should not be tolerated.
You listed 17 schools, plus the 12 schools I listed. That's 29. I think Maryland is definitively better than Iowa, FSU, USC, TAMU, and Tennessee. And Alabama as well. I could make a case for a few others on that list as well to put it inside the top 20, but I could go either way on those.
Regardless I think that top-25 is the absolute floor for MD in terms of HC destination. I think that is different from saying Maryland is a top-25 program. Most of those programs have more recent success than Maryland, but for a prospective coach, potential matters as well, and Maryland's potential is sky-high.
