You might want to take a look back at your timeline. Denver D gave up three points in the first quarter and seven in the second; granted the TD drive started at the end of the first. 

After NY's first field goal Denver went three and out, followed by a NY three and out, then Denver's first missed FG. Then came the NY TD, which was followed by Siemian's first INT which the D forced a three and out, then Denver FG, then another three and out for NY then the pick six and the half.

That's ten points allowed defensively in the first half and three drives three and out. I'd take that any day of the week for a defensive performance through a half of football and I think there are about 31 teams aside from Denver that would likely do the same.   

Being down 10-0 is not a death nail for most teams. Heck, even that stalwart Dolphins offense managed to come back from down 17-0 yesterday to win - on the road even. Down 10-0 is nothing if you have a QB you can count on, Denver doesn't.
