How do we know that he was not coached?
An educated guess based on the rare amount of players that actually improved their skills under Gase.
I am curious as to what you think, overall under Gase do you think the team performed better or worse W/L than what the talent level would have suggested?
Ultimately, Gase was brought in here to take a quarterback who had shown flashes to the next level. After some promising early returns and obviously some injury challenges, the arrow pointed down instead of up.
Overall, I look at players in the secondary being out of position, players at linebacker and in the defensive line constantly getting caught in bad angles. Guys like Cordarey Tankersly who showed promise early on doing nothing a year later. Receivers stopped getting open, Gisecki came in as a pass catcher who can't block and got used as a blocking tight end who hardly gets passes thrown to him. The list of puzzling use of players, in game decisions and personnel decisions because players may have been challenging to deal with goes on and on.
The amount of mental mistakes both in penalties and blown assignments, the amount of injuries year after year, the ridiculous lack of instinct with in game situations, the constant going away from what is working on offense... these all point to bad coaching.
