ENGLEWOOD, Colo. —The full Mike McCoy-offense hasn't yet been installed.

Not even close.

But on Tuesday at UCHealth Training Center, quarterbacks Trevor Siemian and Paxton Lynch got their first taste of an offense that's been lauded as one that maximizes players' strengths and provides plenty of explosive plays. 

This first installation, during the first practice of voluntary veteran minicamp, provided Lynch and Siemian the chance to take the beginning of the playbook from the classroom to the field. And while OTAs and training camp are weeks away and preseason games won't arrive until mid-August, the quarterbacks relished the opportunity to put the lessons into practice.

"It feels good to come out here and have a day to kind of put down the playbook and put some work in and see it kind of live against the defense and get some drop[backs] and throw to some receivers and call some plays in the huddle," Lynch said, "So I thought it went pretty well the first day out. I'm excited for tomorrow."

Perspective, however, remains important whenever a team transitions to a new offense. Not every day will provide a perfect practice. At times, the offense may struggle to adjust.

Both quarterbacks seemed to understand this, and Siemian noted the small steps that must be taken to learn a new offense.

"We still have a ways to go," Sieman said, "but we certainly have enough to get on the field and get some good reps in, which was good. We're going to do some stuff these three days and then add to it next week. Away we go."

Siemian said Tuesday's practice went "better than expected," which is a good start for the group as they transition from Gary Kubiak's version of the West Coast scheme to McCoy's pass-heavy offense.

"I think it's a good offense," Siemian said. "You can find a lot of completions in this offense. I think it's a little bit more on the quarterbacks as far as protections and getting into the right play. But I like it. Obviously I haven't played in a game with it and this is our first day out here, but I think it's going to be good not just for the quarterbacks, but everybody."

Before the intricacies of the offense are revealed, protections are changed and checks are made, Lynch and Siemian will both need to learn the new offense. With the whole team in the same situation, though, Lynch said he doesn't find digesting his second playbook in two years quite as daunting.

"It's definitely cool [from] the aspect that we're all learning it together," Lynch said. "It's really cool to me because you kind of get an idea of how other people … are seeing it and how they're learning it. You kind of find ways to learn it and see how other guys find it easy to learn. You take notes from them and you just kind of discuss and make your way through it as a team."

And on Day 1, the team seemed to do just fine.
