Most bad teams can hang their hat on something. Let's look at the current bottom feeders by division
Dolphins-Have good pieces can they get it together.
Ravens-They've been in most games. They've had no luck at all in tight games. They have not been blown out despite the injuries/lack of depth
Chargers-Phillip Rivers and not much else
Titans-rookie qb but have been very competitve in almost every game. Blown out once vs dolphins
Bucs-see titans but winning more games
Lions-Trainwreck on par with current state of 9ers. Though I'd say they're in a worse overall state IMO with the amount of money tied up in Stafford and Megatron. Though they have a much easier problem to fix. It's "only" their o-line.
Cowboys-Every skill position player seems to have been injured for multiple games.
49ers-The reality is your lads are getting beat in so many different ways. And the beating they're taking in those facets of the game is just so catastrophic you can't fix them in one or two off-seasons in the salary cap modern game.
Honestly 1/2 the losses you can pin on an inept defense. Every thread i read seems to be high on Acker and Armstead. Yet Acker is the guy getting burned week in week out. Every time I watch the 9ers recently i need a bucket of ice nearby because at least once a game he's gonna get burned so hard even I'm gonna feel it all the way in Australia. Armstead has been thoroughly mediocre. Yet somehow these two are the best cover and pass rush options. yes they're young, but you have to show something other than being photogenic on the receiving end of highlight reel plays on espn. Your vet safeties are not helping your young corners by taking repeatedly what seem to be poor angles and decisions.
Offensively plenty has been said in other threads.
