LATROBE, Pa. — On the final play of Mike McCarthy’s first training camp practice, he put the ball in Drew Allar’s hand. The rookie quarterback ripped the ball up the seam, hitting tight end Robert Tonyan in stride on a post route for a 14-yard touchdown. It was a nice exclamation point to close out a final segment of practice focused on the two-minute drill and last-second situations, something that’s a major point of emphasis under McCarthy.“Football comes down to situational awareness and execution, especially in two-minute,” said Allar, who also threw an interception on a deflected pass during a seven-on-seven segment. “Coach McCarthy had a stat that around half of our games are going to come down to a two-minute drive, whether it’s us on offense or the defense is up on the field. As an offense, we’ve got to find ways to execute.”During a lighter, unpadded Day 1 at Saint Vincent College, the quarterback rotation began to come into focus. McCarthy said on Monday that Mason Rudolph will start with the second team and Will Howard and Drew Allar will split the third-team reps. He clarified on Tuesday that the depth chart is more fluid than he initially let on. Rodgers will likely get 40-50 percent of the snaps during camp. Rudolph will be next up in the rotation, but all of the other QBs will get their opportunities.“As we distribute the other reps, it will be pretty balanced,” McCarthy said.The final moments of practice showed what he means. Usually, the first and second QBs get the opportunities in the two-minute drill. That was the case on Tuesday.DK Metcalf opens up about the Steelers' team bonding tripMike DeFaboThe Steelers put 1:14 on the clock and placed the ball on 35-yard line. Rodgers completed a pair of passes to pick up a first down, but the drive stalled there. Rudolph, meanwhile, looked sharp. He completed six of his eight passes during the segment to lead the team into field-goal range. His only misfires came on a pass slightly behind running back Kaleb Johnson that was broken up by inside linebacker Carson Bruener, and a deep ball on the final play that fell incomplete. Howard and Allar did not have a chance in the two-minute segment.“I love getting any reps I can get,” Rudolph said. “That’s how I treated it my whole career. Any rep you can get in an NFL training camp is special. You work so hard for those all offseason your whole life, but I’ve never cared whether it’s two’s, three’s, four’s. Treating the rep like it’s a game rep is the most important thing.”The next situation: 45 seconds on the clock and the ball on the 40. Rodgers completed two short passes and then, with time running out, checked the ball down ahead of a wave of defenders. The offensive players lateraled it several times before they were stopped well short of the end zone.
