Saw this on reddit, which quickly turned into a discussion of "Great blocking vs. Holding" so I wanted to get other opinions and/or start some good offseason rule interpretation/philosophy debate.
On one hand, you see a still picture like this:

On the other hand, you could make the argument that the defender only makes a spin move in front of the lineman and doesn't get to make a lateral step as #292 keeps the defender in front of himself, and you'd keep the flag in your pocket.
On the third hand, context of the play probably matters significantly. Fly sweep to the right? No hold. Draw play to the left?
On the fourth hand, that's an interior lineman and I'm a wing official -- that's not my pond.
So my question for you R's and U's... holding or not? Show your work for full credit.
