With Bobrovsky not likely to re-resign in Columbus, would Jarmo entertain Jake Allen as his starting goalie? They have familiarity with one another and might be a viable solution should the teams start talking. I'm not sure that Army would entertain acquiring a Vezina-winning goalie that is looking to get paid...but with Tarasenko, Soshnikov, Barbashev (and Kostin and Torop in the system), maybe STL isn't such a bad spot for Russian NHL'ers. Don't know that Stillman would have the stomach for it after the Ryan Miller debacle...but it's no scarier than not replacing Allen and leaving this season's fortunes to his peaks & valleys.
Cost of a rental Bob would be significant though and the Blues are already without a 1st rounder once again. Jarmo would certainly target Thomas...so it's unlikely anything could be reached. Ideally you'd expand it to include Panarin...but then the cost becomes astronomical and you can't keep everyone long-term under the salary cap, so any deal with Columbus would likely be an either/or proposition between Breadman and Bobrovsky. I'd think Stillman & Army would have to investigate to see if either were a real possibility...but given the choice of the two, I think Bobrovsky would be the focus knowing the Blues' needs.
