There’s a different offensive coordinator calling the shots for the Denver Broncos from this past season. But Mike McCoy knows his way around this team.

They won their first four games this past season. The then-defending Super Bowl champion Denver Broncos were in the running for a sixth straight AFC West title. Getting back to the playoffs seemed like a somewhat certain bet.

But things went awry. Before you could say Mile High City, the team dropped seven of their final 12 contests. And one of the issues was an offensive unit that would finish 27th in the league in yards per game. It also produced only 31 touchdowns. Far too often, the Broncos dug themselves an early hole. Denver was outscored a combined 94-40 in the first quarter in 16.

Following a four-year stint as head coach of the Chargers, Mike McCoy returns as Denver’s offensive coordinator. He spent four seasons on the job (2009-12). Now he’s back, working for new head coach Vance Joseph. Work is the key word.

“There are plenty of mistakes we’re making that we’re cleaning up, but the good thing about that is we’re coaching off that,” said McCoy to Nicki Jhabvala of the Denver Post in late May at OTAs. “It’s never going to be perfect. Every game, there are plenty of mistakes you look at and say, regardless of the score, here are some plays we should have done better, here is how we could correct some things. Everyone is getting reps right now, so it’s been a productive couple weeks on the field for the players.”

The Broncos added veteran free agents in running back Jamaal Charles as well as offensive linemen Ronald Leary and Menelik Watson. John Elway used six of the team’s eight draft choices in April on offense. That includes first-round tackle Garett Boles (Utah) and sixth-round running back De’Angelo Henderson (Coastal Carolina). There’s a pair of wideouts in Carlos Henderson (3-Louisiana Tech) and Isaiah McKenzie (5-Georgia). The latter figures to be the team’s newest big-play threat on special teams.

McCoy and the team still has the quarterback situation to figure out. But having the well-qualified offensive mind back in Denver is a big plus. It would be surprising if the team’s production on his side of the ball didn’t make a big jump.
