If Ho Sang has shown enough for the Leafs brass to believe that he had a real future with the team, they will sign him, if it comes to that. That he is still with the Marlies, suggests that no offers of interest have been made to Ho Sang, so he's fine.
Kenny Agostino, Kalle Kossila, Nic Petan, Gogolev, Steeves, Semyonov, Bracco, Mueller... have all been more productive the past few seasons for the Marlies. Petan was 1.24 P/G a couple of years ago. Ho Sang is 0.87 P/G
He's not destroying the AHL by any means, so it's not like he's a clear must have for any organization. This is a 25 year old, who has never lived up to the hype, who hasn't played in the NHL in three years, only played 10 games for two points then.... He's done nothing in any league since, to convince anyone he's a top six NHL player.
The talent and skills he has is clear, but that hasn't translated to show anything at a level that any NHL executive would scream, this 25 year old disappointment is showing that he's ready to breakout.
Why do people worry about this crap?
