When the light clicks "on" for Lamar, the nickel will be fabulous with LJ on the outside and Kalu sliding into the NB slot.
Kalu and Jones have upped their game on the outside, A Williams seems to be struggling some with the slot receiver.
Splitting the DB coaching duties to get better attention to the CBs and S seems to be paying off so far...perfect? No, but so much better play overall compared to last year.
Just my opinion of course
