and not just this, he also badly mismanaged the offensive line his entire tenure. he cycled through a bunch of coaches w/ that position group and coming into this year was shuffling players all over the place from training camp to halfway through the season. Had Eichenberg playing RT, then LG, then LT for instance. Flores is a pretty good head coach, obv a pretty good to great defensive coach, but dude just has no idea what to do w/ offense and in this era of the NFL you can't succeed that way as a head coach. The best case scenario is you're Pete Carroll and you get a transcendent QB talent like Russell Wilson and get to a few Super Bowls, but once he got off his rookie contract things in Seattle have not been that great and the offensive side of the ball has been a total mess there for years, hiring horrible OCs, feuding w/ his QB etc.
bottom line is you can succeed as a defensive head coach (Belichick, McDermott, Vrabel), you can even succeed as a conservative head coach (Shanahan and McVay despite their offensive genius reputations are pretty conservative when it comes to 4th down & FG situations). but you have to hire a good offensive coordinator and get out of his way and let him run an offense, or you have to be a offensive wizard playcaller yourself. you can't be a defensive minded, conservative head coach who constantly has his offense in disarray. I don't care who the Dolphins QB is, the way Flores wants to play, you're never going to compete in the AFC w/ teams like KC, Buffalo, Cincy etc who want to put up 35 points every game.
