Let's put it this way: here's what I'll be looking for in OTAs.
Who's the right guard? I have no idea, currently.
What kind of reps are Reggie Gilbert and Vince Biegel getting. (To a lesser extent, you could also say Kyler Fackrell and Chris Odom.) Packers absolutely have to develop depth there behind Clay Matthews and Nick Perry.
Who's the No. 2 receiver? Packers need someone to replace Jordy Nelson. Best guess is Geronimo Allison and J'Mon Moore will duke it out this offseason.
How different does Mike Pettine's defense look? This will have to be taken with a grain of salt. Pettine won't show most, if any, of his regular-season wrinkles in open practices.
How quickly do the young corners come along? Will be interesting to see what kind of reps Jaire Alexander and Josh Jackson get, and how much Kevin King participates.
