Which Packers have the most at stake as preseason opener nears?

While Aaron Rodgers and other established veterans will spend Friday's preseason game in a ballcap, a handful of others have much more at stake, perhaps even their NFL careers.

The long wait for training camp finally ended two weeks ago. In short order, the absence of live action will as well when the Green Bay Packers face the San Francisco 49ers for a preseason tilt.

While more than a month separates the Packers from their regular-season opener, a lot has already happened. The team has gone through double-digit practices and produced an unofficial (and mostly useless) depth chart for public consumption. The complexion of the roster has become clearer, but some significant questions remain.

For a handful of veterans, Friday's exhibition means an evening spent on the sidelines in a ballcap. For others, including several potential starters, the game will begin the process of separating the wheat from the chaff. For those individuals, the trip to California kicks off the most critical part of the year thus far.

Romeo Doubs and Jordan Love

In the eyes of a large segment of the Packers' fan base, Romeo Doubs' has already established himself as a starting wideout and future star. While that scenario could unfold, Friday's preseason tilt will represent his first test against non-teammates since the Senior Bowl in early February. Granted, the 49ers will keep their defense as basic as possible, but Doubs will still have to beat NFL defensive backs in a full-contact environment for the first time.

Part and parcel with Doubs' professional debut, Jordan Love has a considerable amount at stake as well. The Packers have already confirmed that Love will start and see most of the work. Depending on how long the Packers keep him in, Doubs might not see a target from another quarterback.
