This is an open ended question that I thought of while reading Chris's "interesting stat" thread and someone said they missed JP Holtz. Matt Flanagan was pumped up because of his ability as a blocker. He's shown some skill as a receiver but have we used him much as a blocker in passing situations? Using him as one would take away a receiving option but might help a little bit with the pass blocking. If we've used him, I honestly can't remember. Now that the idea is in my head, I'll keep an eye out for it but maybe @Chris Peak @RoadToNumber10 or someone else can answer it.
