Have heard comments from Jonathan Kraft about how the Pats pay the roster players and practice squad players.. so why can't they bring up someone to fill a gap in the event of an injury or specific need??
Consider MLB they bring up role players from their affiliates to fill a need for a short period of time, why shouldn't the NFL do the same??..
The current practice never made much sense to me.. that would also be a better way to assess the talents and abilities of a practice squad player in a game time situation..
