No way man...if you threw 80mph in most high schools, that would put you among the top 5% of pitchers in the conference (and even so, MOST high schoolers wouldn't be able to hit that effectively and consistently). I'd guess the average high school pitch speed to be about 72mph. I'd guess that the average high schooler can hit anything about 74 or lower with consistency, and anything above that takes one of the better hitting high schoolers (to hit it consistently).
Back to my point, there's a massive overestimation of pitch speed these days.
When you ask someone how hard they throw, you can basically plan on subtracting 7-12 mph from their answer to get the truth.
I mean, people have told me their 5'4" 11-year-old is hitting 79 on the radar gun. Let me help you out here: No he's not.
A) Sports Illustrated would be all over a story like that
B) His All Star team would have won the Little League World Series and probably the World Baseball Classic too, because at a pitching mound 46 feet away, that's equivalent to about 104 mph
Bottom line, humans are not radar guns, and I've found that most humans would make absolutely horrible radar guns if they tried.
So true. About 15 years ago, we had a United Way day at work and there were multiple games set up with various donations to play (dunk tanks, etc). They also had a radar gun set up to guess how hard you threw. It was much like the carnival type setup. Anyway, a coworker who ran track in college thought he had a great arm and would be able to throw as hard as me. At the time, I was throwing low 80's topping out at 85. So later in the day when the festivities were done, a group of us went back and tested how good our perception of speed was. In our group of 6, only 2 of us were close to accurate as a guy who knew he had a wet noodle for an arm predicted he wouldn't break 50 and I was able to hit 80 after many pitches to get loose. Most of the group was about 10 mph too high in their estimations. And the guy that ran track? He hit 70 with much effort and strain.
How hard you throw is the baseball equivalent to the workout question "how much do you bench?" Almost universally over-estimated, sometimes intentionally but mostly just from a lack of perception.
