None of those guys you listed are irreplaceable. Given the talent at the position i doubt homer would be a big loss at rb. On special teams that will be a big loss. It seemed like Cager dropped more passes than he caught last year tbh plus Osborn is an immediate upgrade over him at the #2...
Still finished the season better than Dallas, where’s the pitt and duke and va tech game in the second half of the season? He averaged damn near 10 yards per carry vs those 3 in the second half of the season.
18 for 133 duke
12 for 69 va tech
8 for 164 pitt
