Daniel Coats arrived in Denver on Monday and almost immediately started studying his new team’s playbook.

By this morning, the fourth-year tight end was adequately pleased with his progress.

“It’s difficult because it’s a lot different than what I’ve been doing, but a lot of it makes sense, so it should come pretty quickly,” Coats said. “Right now, I’m just working on it.”

As the Broncos began gearing up for the season’s second half Tuesday, they added Coats to the active roster and waived defensive lineman Le Kevin Smith.
