When did he get his injury? Was this something that happened in Calgary that Allvin should have known about?
I think this underscores one key aspect of aquiring players - it's usually a mistake to expect any player having a lousy year and playing poorly to turn things around with a new team.
Benning made this mistake consistently by trading or signing for players whose best years were behind them (OEL, Loui Eriksson) or expecting them to find a new gear (Sutter, maybe Gud) once they got to Vancouver.
With Lindholm you have a guy who played below his expected level all year, in a massive UFA contract year. That should have been a massive red flag. If he was having such a year when he should have had all the motivation to have a great year, that's a problem.
