I like that we got Harrison, but he is an aging fat man with questionable motivation and football fitness. I think that he got some get-your-butt-in-shape snaps against Chicago but is likely more of a backup to give the other guys a breather. I clearly don't expect much out of Harrison.
I would also like to address something that I heard on the Packers OT from WTMJ (and somewhere else that I can't remember). The pickup of Harrison has been compared to the 2010 pickup of Howard Green. I get it. However, I've heard multiple times that Green didn't do anything until the Super Bowl play. That's not true. When the Jets cut him and we picked him up in time to play against his former team, he was a big part of the 9-0 win. I remember it being windy and he had a bunch of stuffs, including a forced fumble. Snacks will probably be the same way. He will show some glimmers and hopefully make a few noticeable impacts, but will likely disappear for most of his snaps.
