From what I've seen, Jalen, while putting up fantastic numbers, still has basically the same issues; slow reaction time, favors the right, poor field vision. Nonetheless, he will put up huge numbers in the Big 12
It's very early, but here is the current tally:
Tua - 1,007 yards, 76.9%, 11.1 y/a, 12 TDs, 0 INTs, 213.4 rating (Duke, New Mexico State, South Carolina)
Trevor - 831 yards, 60.8 %, 8.6 y/a, 5 TDs, 5 INTs, 139.5 rating (Ga Tech, TAMU, Syracuse)
Jalen - 880 yards, 80.3 %, 14.4 y/a, 9 TDs, 0 INTs, 250.2 rating (Houston, South Dakota, UCLA)
