I don't know that this is true. Many NFL coaches have very traditional views on what a NFL QB should look like and Kyler isn't it. RGIII is still hanging around the league but no one is calling that a success story.
I agree with this. Not only in his physical profile but in the systems he can play.
Kyler is broadly playing in the same system he always has since high school, through college and into the NFL. Not identical obviously, but the same core.
That's a lot of years running the same system. Can he go from calling plays that are literally a single number such as 92 or 85, to a Erhardt-Perkins or Westcoast scheme where he has to call FB West Right Slot 372 Y Stick or worse?
And a lot of coaches do 90%+ of their work under center where Kyler does around 10%. He hardly ever runs bootlegs. There's a whole bunch of stuff Kyler doesn't do (and does do) that is the opposite of what many coaches want.
One of my biggest concerns about ever firing Kliff is the limited coaching pool available that would suit Kyler.
