Spencer Rattler named starting QB ; Jay Glazer reports Rattler expected to start next 3-4 games (month) until Carr’s return

He is not more mobile than Carr nor Haener, but he is more willing to run, and his arm strength allows him to throw off platform. Rattler runs a 4.95 in the 40, a 4.37 in the the 20 yard shuttle and a 7.21 in the 3 cone. Those are all slow. It’s his arm, not his legs that have to shine for us to win.

It’s no different from Patrick Mahomes 40 time which is 4.8 and he out ran the Saints defense like he was Michael Vick in his prime. Like Mahomes, Rattler knows how to escape pressure just enough to gain some yards or pick up a first down even though both QB’s 40’s are considered slow by league standards.
