If you have two quarterbacks, you don't have a quarterback.
This comes just a few days after O'Brien said on Talk of Fame Sports Network that he hopes to have a starter in place by "the end of spring or early in camp."
Whereas Hoyer handled most of the first-team reps last week, Mallett was under center with the ones on Monday.
Unless one of the two starts practicing at a higher level, O'Brien might be forced to wait for preseason action to determine a winner.
Here's what else we learned in Monday's OTAs:
- Odell Beckham gave Giants fans a scare when he was held out of Monday's practice with tightness in his right hamstring. Beckham was adamant that the issue is "absolutely not" similar to the left hamstring injury that lingered throughout last offseason and into September of his incredible rookie season.
- Arizona's early-round draft picks have discovered that coach Bruce Arians is dead-serious about making them earn practice reps with the veterans. First-round pick D.J. Humphries, buried on the depth chart, has been limited to the second field with fellow rookies. Third-round running back David Johnson is "not in the picture yet," Arians said. "He ain't getting (expletive) yet."
