ENGLEWOOD—Even if Trevor Siemian was the quarterback of the first OTA, it was difficult to notice with all attention on the quarterback of the future.

As Day 1 of organized team activities goes, Denver Broncos rookie quarterback Paxton Lynch looked good. His footwork is sloppy at times, but his throws can be pretty. As an example, the deep ball he tossed perfectly to Jordan “Sunshine” Taylor for a touchdown.

“As a rookie, nothing really matters what you do in college,” said Lynch, who was selected out of Memphis University by the Broncos last month with their first-round draft pick, No. 26 overall. “You come here, it’s a clean slate. … I have no rank around here. I’m a first-round draft pick but, who cares? We’re all on the same team here. I’m playing with (college) free agents right now. We’re all trying to do the same thing. In my mind I’m trying to earn a spot on the team.’’

Throughout the practice Tuesday at the Broncos'UCHealth Training Center, quarterbacks coach Greg Knapp and head coach Gary Kubiak harped on Lynch’s footwork.

“I knew it was going to be that way,” Lynch said. “I’m sure it’s that way for a lot of guys, especially guys who come out of the spread (offense), who haven’t had a lot of footwork tied to their progressions and reads and timing. And I’m one of those guys who we really didn’t do much of that.

“So they really harped on it. And I think that’s good because when you get in the heat of battle that’s the last thing you’ll think about because you’ve been harped on so much so it’s kind of burned into your brain.’’

With veteran quarterback Mark Sanchez only able to participate in position and 7 on 7 drills because of recent surgery on his left thumb, Siemian and Lynch split the team reps at quarterback. Siemian worked with the first unit; Lynch with the second.

Kubiak said Sanchez should be ready to take team reps next week, which would be 17 days from his surgery.

Only Siemian among the quarterback group is in his second year of operating Kubiak’s offensive system. And it showed. Siemian consistently found the open receiver, although all quarterbacks spent considerable time on the check down and short passes.

“How many guys are asking about him?’’ Kubiak said about Siemian. “I’m really excited about Trevor. He’s got a chance to be a really good player. He knows exactly what he’s doing. He basically took the first group today. … Trevor’s got a lot of confidence in himself.’’

Sanchez wore a soft cast on his left thumb but because he can’t take the snap from center, he did not participate in 11 on 11 action. He did perform well in 7 on 7 passing portion (holding the ball out in front to pantomime taking the snap) other than the interception he threw to linebacker Corey Nelson.

“This was exactly where I wanted to be with this minor setback,''Sanchez said. "It’s no big deal. I’m just taking it week to week. Hopefully I’ll be ready to go next week. I’ll continue along this theme of doing all of this 7-on-7 stuff and taking all of the reps that I can like you saw today.”
