Check their times and quit being fan boi's.
See them both in person... oh sorry, you weren't born yet to pull that off.
Rocket ran a 10.34 100 as a Jr in HS.
GA3 ran a 10.39.

When they got to college and put on pads against Div 1 caliber players, GA3 had a handful of breakaway runs while Rocket was rewriting record books.
Lucas video looks like those of the fastest runners each year. He does seem to read his blockers (and there were some nice blocks thrown) and makes some nice cuts.
I saw Rocket play. I saw Bo have the ball kicked to him when other Div 1 coaches were kicking away from him. Everybody on the UM team knew it was going to Rocket. There were some highly talented and fast players on UM's Special Teams but Rocket make them look very, very ordinary running back not 1 kickoff for a TD but 2.
Seems every year there are Rocket or Bus comparison's for some HS prospect but they've rarely materialized.
