An NFL study showed that, in the pros, RBs and WRs (and TEs)—the “mobile” positions—suffer injuries at about the same rate. Each play in which a WR or RB is the ball carrier poses a risk of injury. If you run a balanced offense, the risk of injury, on average, would be spread evenly among the “mobile” positions. If you run an unbalanced offense, say 75% run vs 25% pass, the risk of injury, on a statistical “likelihood” analysis, will fall much more heavily on your RBs. This isn’t just statistics, it is common sense.
So, RB injuries aren’t necessarily about overwork. Some injuries are simply about statistical likelihood. Football is a brutal game that is very tough on knees, etc. Every play poses a risk of injury. The going-forward statistical issue for me is whether the Gophers, with only two scholarship RBs left, and a full complement of 12 scholarship WRs left, should continue to allocate 75% of the risk of future injury to our 2 remaining RBs and 25% of the risk of future injury to our intact, 12 man WR corps? Maybe our strengths and weaknesses, and our scheme, require that we continue to expose our remaining 2 RBs to a much higher statistical risk of injury. But, if we trusted our passing game, and took account of healthy troop numbers in each “squad” (RBs and WRs), it would make sense me to put the WR corps on the front line a little more often, at least 50/50.
Maybe we don’t trust our passing game as we did in 2019. Maybe our OL is a lot better at run blocking than at pass blocking. Maybe our eat-the-clock, TOP philosophy is so embedded that we stay with it unless and until all RB troop strength is exhausted. I don’t know.
