Doubtful Romo had much say in the offense, being a starter for 10 games or whatever it was in 2006. As Tony grew into the position, he was able to really decide what routes he liked vs those he didn't. I find it hard to believe that the owner came out said "romo friendly" offense and Tony was on the table pounding for exotic routes and over the middle throws and the coaches were like "Nah, we good bro". Everyone that hates JG, claims that Tony ran the offense, was calling the plays, was designing the plays but then they want to blame JG for the lack of slants and crossers. That makes a lot of sense.
In 2006 they were running an Erhardt-Perkins, in 2007 with Garrett the passing game went Coryell.
Tony Romo only started having influence in 2013 when he had the contract and it was forced from above. But even then Garrett was interfering with Callahan and Jerry finally relegated Jason to the sidelines in 2014, but getting Linehan because they didn’t want to completely change the offense they were running for years because of Garrett.
Romo wasn’t in game planning nor had any influence in play-calling until that time.
This was all confirmed by guys like Jerry, Wilson and even Garrett himself, who had no choice but to affirm it openly as making sense that the QB needs to like the plays he’s being called. Wilson himself said that Romo was now going to get to implement his concepts with this change.
What happened in 2014 when Garrett was relegated to just clap? We actually never abandoned the run, Romo threw for 34 TDs and 9 INTs only, while throwing the second least amount of attempts. It was a brilliant display of highly/efficient QB play.
So yes, Romo was calling the plays in 2014 with Linehan, while prior to this when Garrett was running the plays, by the second half Dallas had to primarily go hurry-up and up-tempo because Garrett’s game-plans and playcalling couldn’t do squat.
So these statements Butler correlate exactly with this timeframe. Butler came in 2014 when Romo started taking real control.
