The good thing about Lindstrom is the price. A top 9 player for 700K (if I recall correctly) is a price you can't beat.
I'd like to see him with his natural line (back with Steen and Stastny) before pulling the plug, but the results so far have been predictably mixed.
I see him keeping a spot warm for a rookie player like Rattie, or even for Jaskin to claim. Although he hasn't been able to convert some of the opportunities he's seen, he also isn't a glaring liability in that role. I guess the cut-off point is, when is it worth sacrificing depth by trading or losing a player to waivers to bring up a guy like Rattie. Would Rattie do any better than Lindstrom? I doubt it right now.
I'd like to find Jaskin a regular spot where he can have success. I see him as having more of a future with the team than Rattie does, but I probably underestimate Rattie. If you could put Fabbri in a time machine for a season or maybe two, I'd love to see what he looks like on that wing.
