Yes but there are a few reasons for that. Coming up on 65 games for these teams is the biggest reason. The second is that you will see some - less powerful - schools due to auto bids. Not to say these teams are not good, but you stick Quinnipiac in the SEC and they most likely don't get this far. A team like that is recruiting from a much different pool than a SEC school that missed out on the tournament, just less firepower. The third is that even though the speeds might seem slower that is what these guys cruise at. That is the biggest difference between HS and college pitchers. The guy who is 87 in the 1st will still be 86/87 at pitch 95. In HS that kid is down to 81/82 and probably gassed.
Just proof that 84 can get the job done just as well as 96 when you're on.
