As good as Allen has been I wouldn't gamble on him yet considering his two-way contract. Halak should be manning the net soon enough, it would be a BIG surprise if he isn't, and Seguin is a first line scorer.
If you wanted to gamble on Allen being a better 'tender than Varlamov from here on out then I would think Varly would be the likely drop candidate. Now THAT is something I think you could take a gamble on.
