If I understand this correctly, unless they decide to activate Webb as something other than the #3 QB this season, he won't get in a game unless Favre & T-Jack go down with an injury. Once the player occupying the roster spot designated as the #3 QB enters the game, the #1 and #2 QBs cannot return. In order to get Webb the ball they would have to deactivate someone at another position (i.e. WR, special teams) and activate him in that spot.
