Fillet is definitely worth giving a go. I think there's a couple fo match ups that she's better into (Hunters and morticians at least). My fillet team is princess, boiler, vOx, tenderiser and a proxy Roast or meathook in tournaments.
As for getting the ball back... shank helps (because he can just get anywhere on the pitch). But really, why bother? If it's proving to difficult just get another couple of takeouts. A lot of people talk about a team being 4-1 or 2-2 but don't tie yourself down so strictly - just look for what's the easiest way of scoring vps and adapt to the flow of the game.
