I agree w/you.
Not sure if you remember, but when you put out the depth chart, I asked you if we were only carrying 3 OT's. I think that is similar to the RB situation you described. We saw that unfold last week w/the ejection and an injury. We were forced to move a struggling RT to LT and put a backup interior lineman at RT. Ouch!
