I would not, for a couple reasons.... first, there are two reasons the clock stopped - to administer A's foul, and B's helmet coming off. I don't see why we would give a clock advantage to A, when both teams technically stopped the clock for administrative purposes. If it were just B going down injured: nope, still wouldn't... there's a reason why that 5 minute guideline is there (because that's what they want the guiding time boundary to be, not 5-ish minutes left), and IMO 5:38 is too far away from that - even with clock not stopping, A could easily run 2, maybe 3 plays before the 5 min mark. While it will start on the ready, Team A should be taking this time to get their business together and there is no reason that they can't be ready to snap immediately after the RFP.
