The most entertaining NFL camp battles will involve highly touted rookies attempting to supplant veteran players and justify their selections in the draft. For example, the New England Patriots will naturally expect first-rounder Dont'a Hightower to start right away at linebacker, yet Brandon Spikes is unlikely to let his job go without a fight.
Then there are those battles involving previous prime draft selections who have yet to live up to their billing and now face immediate competition. Baltimore Ravens' 2010 second-round pick Sergio Kindle faces a challenge from this year's second-rounder, Courtney Upshaw.
Meanwhile, in Miami, Cleveland, Tennessee and Seattle, all eyes will be on the impending quarterback competitions. Brandon Weeden and Ryan Tannehill must justify their high draft statuses and answer the criticisms that they were draft reaches.
Here are the most entertaining training-camp battles to watch for each team.
