The next question is how the Chiefs replace Boss at tight end.
Here's what the tight end depth chart looks like:
Moeaki is good depth behind Boss, so the potential is there for the Chiefs to capably replace him. They had planned on more two tight end sets this season, which helps with the rushing attack and the play-action, but that plan may need to be tweaked.
What's concerning is that the Chiefs are one play away from Steve Maneri and Jake O'Connell being featured in the offense. That's not a good situation, but that's what happens when you get down to your third and fourth tight ends.
The loss of Boss means more snaps for Moeaki, who has seen his playing time rise in the wake of Boss's Week 2 concussion.
Moeaki staying healthy just became a lot more important.
