ORLANDO, Fla. -- Doug Marrone has no illusions about the Buffalo Bills' offense.
"We have a lot of work ahead of us on offense. We really do," Marrone said this morning over breakfast at the annual NFL owners meetings. "Coming together and putting everyone in and being more productive, we're not close to where we want to be right now."
In Marrone's first season as head coach, the Bills ranked 22nd in points, 19th in total yards, second in rushing yards, 28th in passing yards and 29th in third-down conversions.
Marrone brought in a pair of coaches to help offensive coordinator Nathaniel Hackett and second-year quarterback EJ Manuel.
Marrone took away Hackett's quarterback-oversight responsibilities and gave them to former Detroit Lions assistant Todd Downing. Marrone also added former Baltimore Ravens receivers coach Jim Hostler as a senior offensive assistant.
Asked to elaborate on not being satisfied with the Bills' offense, Marrone said it shouldn't be considered a secret.
"I don't think anyone should feel, 'Oh, my God. I can't believe Coach said that,' " Marrone said. "Coach Hackett knows that. EJ knows that. I think our offense knows that.
"Are there some things that we did well? There were some aspects of how we ran the ball well. There were some concepts that we did well. But when you look at us overall, the amount of touchdowns that we scored and overall third-down efficiency, it's not good enough.
"The team we want to be, we have to get better in those areas."
The Bills have only tweaked their offensive personnel so far. All of last year's best playmakers remain on the roster. They added left guard Chris Williams and third running back Anthony Dixon in free agency.
From a schematic standpoint, Marrone noted the Bills' 2014 offense won't look different to the naked eye.
"It might be a middle triangle read instead of an outside read because EJ's done a better job at middle triangle reads," Marrone said.
"You're not going to look out there and say, 'It's a whole different team now.' But things that he does better, we'll do more of those things. Things we need to do to defeat certain coverages that people played against us, we'll work on those."
