His fastest 100M was a 10.98 as a Soph. Ran a 11.01 as a Jr
I wouldnt go as far as saying his speed is elite by any means, but for a QB he's serviceably fast.
Realistically, with Slovis running a 4.55 40 at the NFL Combine and Puka running a 4.57 (Puka's best 100M in HS was a 11.01, which Hillstead matched as a HS Jr) probably mean's McCae is about a mid 4.5 40 like both Slovis and Puka.
