When the New York Jets take the field for training camp this summer, their starting roster will look a lot more stable than it did last year at this time.

Thanks to their offseason moves—which included fortifying the top of the depth chart at wide receiver and cornerback and the bottom of the depth chart on the offensive line and at running back—the Jets have the look of a much more competitive team in 2015 than the one that took the field just 12 months ago.

Ultimately, though, their actual level of competitiveness will depend on the kind of performance they get at the quarterback position—which has been the shakiest position on the roster for years and appears to once again be the shakiest position on the roster in 2015.

Though the quarterback battle will likely steal most of the headlines, plenty of other battles could steal the show. With help from some observations in spring practices, we can already get a feel for which players will come out on top in those battles.
