The real reasons for the losing streak are quite numerous, but what they all have in common is an apparent inability to solve the problems. I am so disappointed with Sunday's game not just because they lost and played badly, but because I really believed (call me naive) that changes would be made during the bye break. But no. OL still sucks. QB still erratic (though he had precious little time). Running game nonexistent (Rice and Pierce may be off their games, but how many times did the runner get nailed in the backfield when he had just gotten the ball?). Predictable play calling. Special teams blunders. Defense unable to make a stop late in the game. It's all the same garbage floating to the surface, and no one (read head coach) has either the ability or the stones to make the changes to clean it up.
It is certainly possible the Ravens are suffering a Super Bowl hangover and just don't have the intensity needed. It is likely they just do not have the talent to win. But it is the coach's job to put the players in situations in which they can succeed, and if they're not to make changes to find a way. Harbaugh said they were going to, and they did not. I find that discouraging. I don't expect him to get canned during this season, but I bet he'd better show some willingness to fish or cut bait or he may not be back next year.
I was thinking earlier about what is a head coach's real role.
1. teacher (obvious, I would think)
2. motivator (shouldn't HAVE to be with grown adults, but that seems to be a prerequisite for a head coach)
3. organizer (plans meetings, etc.)
4. problem solver (BINGO!)
#4 really jumped out at me when I broke it down that way. There are constant problems that crop up, and a head coach (as opposed to a position coach/coordinator) is more involved in the management aspects of the team than the day to day x's and o's. And it's in that role that I feel that John Harbaugh consistently comes up empty, or less than full. He constantly says the same thing: "We need to fix x,y,z". The PROBLEM is...x,y,z never seem to get fixed, especially when it comes to his underperforming coordinators. So the fact that he's not a really good problem solver means, by default, he's just not a really good head coach.
