That's the knock on Roman is that he will be good for a season or two maybe three and that's it. How come it's the same issues that come up on every team he goes to? His situational play calling sucks. He always has communication issues. He doesn't adjust game plans, Red Zone scoring issues etc.
All you have to do is look up his history with his previous teams to see it's just the same issues time after time with him.
This is from a previous article:
In 2013, the San Francisco 49ers were penalized 13 times for delay of game, the most in the league. In 2014, the San Francisco 49ers were penalized eight times for delay of game, sharing the top spot with the St. Louis Rams and Washington.
In 2015, the Bills are second in the league for the penalty with four called, behind four other teams who have been dinged five times. One could argue Greg Roman is the common element.
Penalties are not the only thing people associate with the negative of this offense. Counters, runs up the gut, and draws on 3rd and long seem to have carried over from Greg Roman's time in San Francisco. Don't forget the inability to convert in the red zone for several games.
Now with the Bills:
It all goes back to an issue that haunted the team last season.
With Roman calling the plays, Buffalo has not shown the ability to consistently convert third downs and sustain drives. In 2015, the Bills converted on 86 of their 227 third-down chances, a 37.9-percent rate, which was No. 21 in the NFL.
I can go on and on pasting the same from other articles. It's a cycle with this guy at this point. He has to go or we will continue seeing the same mediocre team.
Sorry for the long post lol.
