Perhaps there is a dynamic where Danny's mind set was "Do what Bubba would do." where Isaac having less ties to Bubba is of the mind set "Do what it takes with what we got". He also probably watches Simon struggle with pass placement and knows in practice Simon is not struggling with those throws, a mental thing that can be fixed?
It seems the common take on Simon's issues, other than the Hedburg on a Bicycle guru wannabe, is he is rushing things, impatient, and learning the level he is at... I don't even know where a Holiday Inn is anymore, so is my take accurate.
Slippery slope to advance players based on their 2nd level attributes, best man to win the game seems like a good approach, how Bubba & company function is a head scratcher, being a coach would be almost as !@#!$ as an LEO these days.
