and former Rider DL Aaron Crawford signed to PR.
Crawford : NI , played LB at St. Mary's. Drafted by TOR in 2012, early cut by SSK this year. Sounds like CDN depth, STs. Long snapper too, which is probably the key here.
If indeed Crawford is a Long snapper,with King being questionable for this game and being our 2nd string Snapper,then this would be the obvious reason for this aquisition,as he could replace King on s.t. and back-up Scott in case of injury.
