cong,
No. I don't think 7.0 60yd speed would have beat those out. They'll just have to get more pop to move the right fielder back to get away from that. I don't think the right fielders were playing much deeper than 220' and with a few steps in while the ball is in the air they really didn't have long throws to first.
Our HS clocked the players and the times for all the freshmen except for my son were surprisingly slow. His times were slow, I just wasn't surprised in his case (he was actually .2s faster than I'd expected).
