Fleming is probably a tenth of a second or two faster, but both pretty **** close speed wise.
Fleming is naturally fast I mean crazy fast, his brother is probably faster than him & they're both pure speed demons.
But more importantly, Fleming has deadly short area quickness, he understands how to get open & runs very crisp & clean routes, has good hands too. Fleming is more sudden with quick-twitch ability.
Mookie is basically just Jeff Thomas 2.0, but with a maybe a little less gifted as a pure WR. Mookie is more of a RB/Slot Back type, Idk if he's a #1 outside WR the same way JT4 is, more of a WR2 or Y-WR in the slot.
