I'm glad they didn't punt. Punting at that point is basically saying you're okay with the tie. I would never be okay with the tie. I'd rather take the gamble and lose, than meekly accept a tie.
Now, I agree that the 62 yard attempt is not a good idea, especially in the cold, and that going for it on 4th and 10 is the better call. But I won't fault Kubiak too much for that.
