My answer is yes, but the second “RB” should be Samuel most of the time. Samuel 4/5 to Johnson 1/5 times. There is bound to be a LB covering that second RB or Cook. Split that guy out.
Also, agree on 12 personnel. Cannot recall this season seeing us line up with Knox and Kincaid on opposite ends of the line before, as above, the latter splits out to take a LB with him.
I’m sure it’s happened with both formations this year, but I have no specific memory of it.
