Most offenses are tailored around not just the QB but the other personnel. The Pats offense is Brady friendly, the Saints offense is Brees friendly etc. OCs need to adjust to the personnel or find the personnel to fit. It's not a big coincidence that the Saints went 7-9 3 straight years until they found their Bush/Sproles replacement in Kamara. The Pats are designed around a short passing game because of Brady's lack of scrambling ability, that's why Welker then Edelman work well in their system. Brady would get killed trying to run the scheme used in Green bay which is based on Rodgers scrambling and deep passing. The Seahawks offense is based around Wilson and personnel , heavy number of rushes(most in the league) and PA passes. They tried more passing and have Russell carry more of the load, it had mixed results at best, wasn't working all that well. They went back to run first, run often and got back to their groove. He's only thrown for 300 yards once all year. After Wentz got injured last season, they adjusted their offense to Foles, it became Foles Friendly.
Linehan struggles to adjust his system. Not just adjusting to Dak but adjusting to our WRs/TEs, he was calling plays like we still had Dez/Witten, big bodies that won battles with size and experience. That was a disadvantage for guys like Beasley, Tavon, Thompson, Gallup. Those stop and comeback routes had them at disadvantages, where we should have been using more motion based offense, slants, drags, crosses, stacks, bunches to let them use their speed and quickness
Trying to use the term "Dak Friendly" as a slur is simply a cop out, all offenses should be friendly to their QBs, only in Dallas is that a negative thing.
