Broncos minicamp observations

ENGLEWOOD, Colo. -- Notes and thoughts from the first day of Denver’s mandatory minicamp:

First-round pick Tim Tebow struggled some. He threw two interceptions and was off target at times. Denver coach Josh McDaniels still praised Tebow’s progress in learning the system. However, Tebow showed it could be a lengthy process.

Meanwhile, McDaniels said he hasn’t made up his mind yet, but he is leaning toward keeping two quarterbacks active on the game-day 45-man roster because having more would “put us behind the eight ball at other spots.”

McDaniels said he hasn’t decided who his two quarterbacks would be if he goes that route. Currently, Kyle Orton is the starter, Brady Quinn is the backup and Tebow is third string. Even though Tebow has a long way to go, it would be a surprise if he is a game-day inactive.

Star linebacker Elvis Dumervil downplayed whether he will sign his restricted free-agency tender by Tuesday. Dumervil attended the minicamp, but didn’t do team drills.

“It is what it is,” Dumervil said repeatedly. “We’ll see what happens … Time will tell.”

McDaniels also downplayed it. He said the team sent a letter saying it would reduce Dumervil’s offer if he doesn’t sign his tender by Tuesday. McDaniels said the letter is a formality and he expects the situation to resolve itself.

Denver's other first-round pick, receiver Demaryius Thomas, had an up-and-down day. He made some nice grabs and ran some nice routes. But he also dropped some passes and struggled in some routes. McDaniels deemed it a “typical day” for a rookie. The Broncos expect Thomas, taken at No. 22, to contribute right away.

Linebacker Robert Ayers, a first-round pick in 2009, didn’t do much at all. McDaniels said it was a coaching decision. Ayers needs to bounce back from a weak rookie season.

Tight end Richard Quinn, a second-round pick in 2009, has dropped several balls in practice and he has been slow to develop.

Rookie offensive lineman Zane Beadles worked at left guard after working at tackle earlier in the offseason.

McDaniels praised the conditioning and leadership of veteran defensive tackle Jamal Williams, who signed with Denver after starring in San Diego for several years. McDaniels said he expects a big contribution from Williams.

McDaniels said linebacker Darrell Reid’s rehabilitation from knee surgery could extend into training camp.
