St Louis is building for the future. They don't need Biron or oft-injured Kalinin. That trade is totally self serving to Buffalo, and addresses none of what St Louis will be after- picks and prospects.
Albeit Novotny is only 23 he's a decent prospect at best. The Blues will get way more for those 3 in the open market than what you propose- a slight upgrade in goalie, an oft injured defenceman, and mid level prospect.]]>
I'll be surprised if the Blues are trading partners with the Sabres, Tkachuk and Guerin both make way too much for the Sabres to afford them.]]>
