Just tried out CoachGlass with Madden tonight and it's really a cool feature and worked perfectly on my old Samsung tablet. I didn't realize this feature was added to the PS4 version with this year's game. If you haven't tried it out, it's definitely worth taking a look at.
Here's a link to all the details about it: Madden 15 CoachGlass (http://www.easports.com/madden-nfl/news/2014/feature-details-coach-glass)
Here's a video for it:
