Before he signed the contract, he scored at a pace of 29 goals or more more per 82 games, for 4 straight seasons.
He WAS not a play driver. He WAS a goal scorer, plus brought intangibles. IF he could still bring those things, he'd be worth his contract. BUT, I don't think he can - no big summer of fitness will bring the old Gallagher back, unfortunately, I would guess.
But hopefully he focuses more on agility, endurance, and losing weight than on bulking up for in tight battles. That's just less a part of the game now.
