Many teams lose their starting RB during the season for various amounts of time. The Bills like to share carries with two backs. I would consider our "back up" RB to be a starter. I am confident Beane will fill RB2 and well. But, it is important and essential. Especially with Josh Allen being in year 3 and needing weapons, but, surely don't need to handicap him at the position. And, the Bills have an awesome team this year and can make a good run into the playoffs So, why risk a great opportunity when you are one injury away from potentially Yeldon starting.
Beane's got this!
