Its also been said more than once that assistant Tony Sparano was very instrumental in helping not only with the OL, but breaking Garrett's adjustment as an novice OC caller.
Even teams like ravens publicly came out as saying how " simplistic" Garrett's offense after they beat us.
The tendencies were easily to detect and they could counter scheme.
Garrett doesn't adjust in game well or been known to throw anything unique or differently besides his basic 90's oriented rhythm time based
offense. The time based pass game places emphasis on vertical passing but if there is not variations, schematic design, then it will go for naught as teams can counter scheme what you like to do best.
Garrett was criticized for not being able to scheme free Terrell owens, just as his OC mate Linehan was criticized for not ebing able to counter scheme opposing teams, that was counter scheming Linehan - ala bracket coverage vs beasley.
Garrett relies heavily on his OC's to better the offense, vs he himself being able to interverne and better the offense for the OC's.
He has been scrutinized for not going for the throat kill on certain 4th and one crunch time calls, and we've seen him
pressed to try to become to more aggressive - after he's faced the criticisim of Not going for the throat kill (ala vs Houston in 2018)
