ENGLEWOOD, Colo. -- Here are some observations from Denver’s second minicamp practice being held on Wednesday:

• It’s interesting to see Peyton Manning operate in quarterback drills when they work as a group. While the other three quarterbacks worked on roll-out passes, Manning acted as a pass-rusher to simulate a game situation. It’s just one of the many ways Manning helps his team.

• Manning aired out some nice passes Wednesday as his progression continues.

• Knowshon Moreno is progressing and doing some seven-on-seven drills as he comes back from his torn ACL.

• Sixth-round pick, linebacker Danny Trevathan continues to look good. He is getting some nickel looks with the first team and could get some playing time if D.J. Williams’ six-game suspension holds up. Trevathan, a tackle machine at Kentucky, is definitely a player to keep an eye on.

• The Quinton Carter-Rahim Moore rotation at safety continued with Moore getting the first-team repetitions Wednesday. It was Carter’s turn Tuesday. Expect the rotation to continue through training camp. In the end I expect both 2011 draft choices to play a lot with free-agent addition Mike Adams.

• Running back Mario Fannin is looking solid as he tries to make the team. A touted undrafted free agent from Auburn last season, Fannin missed his rookie year with a torn ACL.

• Veteran receiver Brandon Stokley still knows how to play football. He has brilliant hands and his routes are flawless. If he can stay healthy, the 35-year-old Stokley can be the slot receiver.
