Paul Byron made the big jump last season, going from being a pretty good but not quite NHL-caliber forward to being an everyday player. His speed and hockey sense made him a valuable commodity on the team - a player that Bob Hartley could slot in basically anywhere and with any linemates and get value out of him.
He continued this strong play in 2014-15, but he just couldn't bury a break-away chance.
You could tell the Flames really missed Byron during the playoffs. He's fast and small, but plays physical and is a strong back-checker. And for the second straight season, when he was healthy, he was one of the Flames' most consistent players.
