Well, it's debatable either way. I think the design of the play is to hope to freeze the DE or OLB and give time for the RG to pull and set up the block. I think it is a combination of the defender expecting some kind of trickeration by the 49ers, which they do a lot, and the RG just not adjusting. I hope the 49ers don't scrap this run because it didn't work this one time.
Direct TV is an option I am thinking about for next year. I stream games online for free right now on game day, and typically watch the RedZone when the 49ers aren't playing. However, it doesn't have the best quality, and next year I might get DTV Sunday Ticket.
