The RB Solution
Minor trade, bring us a guy with enough talent to contribute, and potentially saves Podolyak's ass.
Jaylen Roberts
Best guess now is that we keep Roberts active and involved, use Schweigert as the RB1, and perhaps keep Podolyak as a utility guy. One FB will be active, used as a gunner, but we'll plug in a TE to actually play fullback.
Net effect of all this: still 4 roster slots dedicated to RB/FB, but now all 4 active (net +1). Chemistry effects likely will suffer, as Roberts as the new group leader will only carry an 80 personality, he replaces a guy with 99.
