It's a 12+ Team Rating player, so he'd better be efficient.
If you keep him, turn him into a killer (and save money for the time he'll meet stronger than him, to buy another wolf).
Look big then : if you roll a double, get Dauntless, and if another, get Multiple Block !
What about a werewolf than can tear apart big guys, mummies, and later pairs of dwarves (with claw, dwarves are like wood elves

).
Make him a pain, so that your opponents will have to flee him or kill him (and if possible, using a lot of players and energy to do that).
He can even still be scorer, but more on the running side (a handoff behind your line is safer than a catch on the other side).
The other option is to retire him and start a brand new wolf. But it's a risk, since the wolf is very expensive and easy to break until he got block.
