Maryland deserved a 2-seed.
The top 16 teams get 1-seeds.
Maryland is not in the top 16 in the coaches poll, D1 baseball poll, Baseball America, etc.
Maryland is not in the top 16 in RPI or ELO.
Which of the 1-seeds would you replace with Maryland and why?
Outside the Big Ten, Maryland didn't perform well this season. They played Mississippi 4 times and lost 3 -- Ole Miss had a losing record this season. They lost to Hawaii, who is not in the tournament. And they lost to a couple heavyweights, Vanderbilt and West Virginia. Those were the best non-conference opponents Maryland faced this season (top 100 RPIs), and the Terps went 1-6.
That said, I do agree putting Maryland in the #1 overall Wake Forest regional is brutally harsh. I do hear you on that.
