We almost limped to the playoffs last year with a depleted team, so SP is not a bad coach at all.
Still, his offense was outdated for about 3 years and he didn't seem to have any desire to reinvent it like he has done so many times before. Forcing Jameis to run QB like a 41 year old DB was proof of that. There was just so little creativity in his playcalling or scheming, even taking into consideration how bad the playmakers available were.
It looked like someone who has been playing Madden for 7 hours straight and is just bored.
