If you're going to have Smith on the roster, he's going to have to play at some point if the #1 is hurt. It may be force-feeding Smith the position, but there's more reason to play him than McCareins at this point. We know McCareins isn't very good. He can show flashes occasionally, but we know he's not a player. Smith can be a player down the line with his athleticism. This point of the season is meant for player evaluation and giving the young players a chance. That's exactly what this is for.
