It's a steeper hill, but yes, we can still win it.
Losing Earl of course sucks, but the timing could be a lot worse. Terrell now has a whole quarter of the season to integrate into the secondary before the playoffs even begin, and he still has Kam to help him into position, and Sherman has been shadowing #1 receivers, so he won't be left alone against the conference's best.
Terrell has also been here for a couple years already, so it's not like we're replacing Earl with a rookie, or even someone new to the system.
And really, how many secondaries boast 3 all-pros in 4 positions? As long as he's even average, our defense is still the most loaded in the NFC.
Again, it's a setback, but an offensive injury at this stage would have been much more devastating. If our o-line levels off, our talent on offense can win a shootout if asked to.
