Maybe he did hit a 1.8 one time. Nothing surprises me when something is hand timed. There are a ton of kids who have hand-timed 4.4 40's but run 4.6 or higher when electronic timed
There was a kid at our local high school who consistently put up excellent pop times and replicated it in games and threw everybody out. But, he was small, 5'8" 130lbs. O.K. HS hitter, looked to hit oppo base hits.
As a defensive catcher, he had D1 skills, but did not project as far as size or as a hitter. Lots of D2/D3 interest, but he chose to go to a large state university and pursue the major he was interested in.
