Why does Rob Gronkowski have his own cereal?

So, this image has been floating around twitter today. Apparently Rob Gronkowski has his own cereal now.

Is Gronk the new Ochocinco? Except of course the difference being that he is at least intelligent enough to grasp the Patriots offense.

There were rumors that Gronk was going to develop his own reality TV show. All of this is very un-Patriot like. Wonder if Kraft and Belichick might have another talk with him if that every happens.
