It's obvious the players like Jason Garrett as head coach because Garrett takes it easy on them and covers up for them. There is no fear of the head coach. Garrett is their buddy who has their backs, so the players don't fear losing their jobs if they continuously screw up on the field, especially the highly paid players like the Oline.
Does anyone believe these players would feel all warm and fuzzy with Jimmy Johnson if he were their head coach? Hell no!!! Jimmy would be busting their tails during the week in practice, and benching anyone, regardless of payscale, if they committed dumb but costly penalties during games consistently!
Jimmy's players hated him during the week because Jimmy would bust their balls while punishing them if they hurt the team on the field. Garrett does the opposite. He babies them, hence the weekly game-costing penalties!
