Enjoy your Tuesday quack:

• Ron Richmond writes about Justin Hoffman's transition from player to undergraduate assistant. The former walk-on from Churchill recently made public the end of his playing days after a string of concussions, the last of which saw him miss the final third of 2011.
• Jeffrey Martin has a feature on the role the University of New Hampshire played in Chip Kelly's development as a coach. The best part of the article was probably this exchange:

"That would buy a lot Freeze Pops, Charlie."

"Mac, we could have bought the entire company."

• Ted Miller wraps up the preseason positional reviews, with USC and Oregon coming out on top with the most groups in "great shape" and no positions of worry. Miller also has a post on the Pac-12 network reaching an agreement with the National Cable Television Cooperative.
• If you want more positional previews, Bradon Oliver has one on the quarterback position. Oliver also takes a look back at the 2009 recruiting class, which included Michael Clay, LaVasier Tuinei and Cliff Harris (insider only).
• FishDuck has another defensive tutorial video this week, this time focusing on the Ducks' blitz packages.
• Finally, Athlon sports has a ranking of the conference linebackers as well as the Pac-12 basketball coaches.

Go Ducks!
