I hate how posters here turn into Captain Hindsight when a move works out well for a team, like it was the most obvious move ever. People last year were saying the exact same things about Gaborik, about how he was a band-aid and he was washed up compared to those 40 goal seasons.. The Kings traded Matt Frattin, a second, and a 3rd for him.. Not exactly selling the farm. The Kings weren't "true" cup contenders last year. Yes, they had won a cup recently but they had a substandard regular season and nobody was picking them to come out of the West.
We need to score goals, and we need a RW to do so. Nobody here wants to give anything of any value up, so obviously our options are limited. In terms of those limited options, I think we could do a lot worse than Lupul.
