Peterson is always a threat on offense. Patterson is dangerous in the kick return game, and guys like Jennings and Rudolph are no slouches either. Their offensive line could be excellent if Sullivan returns from that cheap shot given by Suh; when healthy, he's arguably the best center in the NFL. Watch out if they decide to run right with big Phillip Loadholt leading the way.
On defense, they have a few nice pieces, but not much proven talent. Robison was solid last year, but he benefitted a lot from Allen on the right side. They gave Everson Griffen a huge contract without him proving that he can be a starter. Shariff Floyd, Xavier Rhodes, and Anthony Barr are talented, but unproven. Harrison Smith is a key piece at free safety, but they have a lot of new pieces in their secondary, including Captain Munnerlyn.
But I think that if we contain Peterson somewhat and shut down Patterson, we stand a great chance of winning this matchup.
