In Todd Haley's 46 games as Head Coach (including the one playoff game) his teams lost by 20 or more points 13 times, including 5 times in 13 games this year.
5 of the blowouts happened in Haley's first season, when he had a very young bad team. Those kinds of losses are likely to happen with that kind of roster, so it's not necessarily surprising that we got slaughtered so many times in that season.
But the next year, we won 10 games and the division, but we still got pummeled by 20+ points 4 times, including the regular season finale and the playoff game, both at Arrowhead.
Then this season, we were demolished 5 more times, including the first two games of the season, making 4 consecutive blowouts, 3 at Arrowhead. Something was very wrong, beyond the injuries. The team bounced back strong for a while after that, but then the beatdowns began again.
We've been slaughtered 9 times in the last 30 games, many of these blowouts coming at home. That's a disturbingly high percentage, especially since the roster is significantly stronger than it was in 2009 (obviously this year's injuries played a big part in the losses, but even with the injuries there were too many games where we should have been competitive but weren't.)
Significantly, Haley's teams lost by a humiliating 30 or more points 6 different times, including 3 times in 13 games this year. (Our other 2 blowouts, including yesterday's were by 27 and 28 points, still basically 4 TDs or more.)
When a team gets demolished that badly, then you have to wonder if the players have given up. To have it happen 6 different times in less than 3 years (5 losses by 27 or more this year alone) means that there were quite likely games where the team did give up. That is extremely damning for any coach.
