They play two different positions. CJ is in the game in passing situations. He is a good cover LB and speed to the outside. Nico is the MLB on running downs. He is a better run stopper than CJ. CJ leads the team in tackles with 67 and Nico is second with 44. They are both very effective in what they are asked to do.
I understand that they have 2 different roles on the team. What I was saying is that Nico did a very poor job most of the night against the run. I am hoping that he just had a bad night and he will play better the rest of the year. But regardless, Nico, who is supposed to be our best run stopper, was not good at stopping LSU.
