Not many stars in the bunch, sure, but 16 guys who played 400+ games in the NHL. That's not exactly just a bunch of fringe players - those are legit NHL players. 8 players drafted in the 5th round or later played 250+ games, which is an excellent return on late round picks.
The lack of high level talent is disappointing, yeah, but the Leafs still produced a solid number of guys that had legit NHL careers.
