My comment was more to do with the sweep being just about Boyd's only play. Nothing to do with the sweep play itself or other teams using it. I'm sure we are capable of pulling it off, if we can get our execution right (which has been a big problem all year) but beyond that Boyd rarely supports up the middle for offloads as a good fullback should, and when he does, he can only run about five metres before stopping and palming. If Isaako is going to be learning watching Boyd (in attack), he needs to show him a bit more than a sweep play.
