How so? He's still 55% on the dots, PKs, and wears an A.
You don't need him to score points. If he can be a veteran Blair Betts for this team as 1-2 year stopgap as a role player, it's needed.
That doesn't make him a good player. That means he can win face offs at a pretty high clip and has been chosen to play during the PK and to wear a letter.
Brett Howden kills penalties here, but that doesn't mean he's good at it.
Rooney is a better player.
