Velocity question for past college

im a true submariner, throwing around my ankle, im sitting 76-78 touching 80 w decent movement on my pitches, what have you seen true sub guys not side armers(Darren O’Day, Joe Smith) throwing at any level of pro ball(independent-MLB)

Ive played indy ball for a few years and 79-81 was the highest out of any sub guy that ive seen. He was a decent pitcher, but it obviously wasnt because of his velocity. He had a good slider, movement on his fastball, and quality change up. I believe he ended the season with an ERA around a 4.2… not great, not terrible. Oh yeah, he kept the ball down which is a must with sub guys.
