Was the play where Apple got faded by Kupp in the 4th a bad play by Apple?

[*Synric*]

Eli Apple bites on the double slant. If you see pre snap he takes a couple small steps inside. When Kupp fakes the Slant it leads Apple a little more inside giving him room to break to the outside front corner.

As for doubling Kupp that would have taken a guy out of the box near the goal line. Really it was a well set up play and an excellent fake and route by Kupp. Apple got set up pretty badly.
