Our freshmen threw from mid 60's to mid 70's last year if I remember correctly and were slightly above average for the league. The same kids are throwing from high 60s to 80ish this year and seem to be a bit more above average than last year. Most of them were 14yo freshmen so an improvement relative to the league is understandable. The softest thrower is the one who was a 15yo freshman who was done growing at that point, but he is a crafty lefty and does fairly well as much of the "softness" is by choice.
On the other hand another team in our league has a just turned 15yo freshman coming in who is expected to play JV ball who throws consistently in the low 80s with good command, a lot of experience on the national stage, and some pretty decent breaking stuff. Tough league.
