I get the desire to bring in a more dependable back. Love had some moments this year but other times where he was ineffective. McCray had a lost season this year and has also been ineffective since the 2021 Penn State game (37 carries for 112 yards).
That said, I haven't seen a many intriguing RBs in the portal but I'm sure Illinois would be a great landing spot for one based on the offense and Bielema. The caveat is bringing in a RB seems like it would trigger one on the current roster to leave. If you bring in a good junior RB, would Love immediately leave? What if someone like Laughery isn't seeing available playing time and enters the portal? In this perspective, the RB you bring in has to be viewed as a trade acquisition.
Personally, there are plenty of blue chip guys (Love, Laughery, Feagin (probably a year away)), proven commodities (McCray), and intriguing skill sets (Anderson) to believe you can leave things be. If anything, I would be interested in a RB that has proven more in the pass game, both blocking and catching the ball. But again, bringing in someone likely means someone in the current RB room will leave for a better opportunity.
