Therien was criticized heavily last year particularly by Flyer fans and Simpson I can't really comment on, haven't paid enough attention to. Would be sceptical if only because we'd have to expose another player off the roster.
They are both solid defencemen that play physical and use their body effectively. Chris Therien was pretty solid against us I thought, and he will be a good player for the Leafs to have....
I've also liked Therien....he always seems to up to play against the Leafs.....some of his better games have been against Toronto.....He has great size and plays a physical game PLUS his salary is not too high by NHL standards and would be a good solid pickup by Toronto......maybe the Leafs could pick him up now and then later on in the season try to swing a deal with someone else right before the trading deadline for a solid #2 or maybe even #1 guy for our blueline.............just my 2-cents on the matter.
