Can't tell if you are being sarcastic about the "culture" thing. I think the talk about culture is overrated. Sure, it's important, but X's and O's are more important these days. Playing the right scheme and to the players strengths is what counts. Supposedly, USC had a horrible culture under Helton? Riley just brought a better system and some better players.
If Mario doesn't totally scrap the passing game that worked so well for us at the end of last season, we are probably 4-0 and everybody would be talking about how Mario changed our culture and that was the reason we are winning. We definitely needed an overhaul in the running game and Gattis was a good fit for that. I just don't understand why he couldn't keep some of the passing game that was successful last year. Why can't he go to TVD and the offense and ask them what worked well for them in the passing game? Keep some of those plays in the play book just in case the new passing scheme/plays are not working.
