eh, how far have the Titans gotten with CJ2k and now Derrick Henry? 49ers and CMC(Panthers too)? Zeke? Aaron Jones? Sure a great Rb is nice to have, but a standout Rb doesn't harbor much advantage over 3rd round rookie. Chiefs had Pachecko. Rams had sony michel- 1st rounder but no way a great rb. And yeah that list is a little misleading, but even with those execeptions...they didn't lead the team in rushing during the SB. And without those execptions? The winning team(and even the loser in most cases) didn't have a top 5 RB.
FWIW Henry was oh so close to taking Tannehill and the Titans to a SB.
