Last year I used my phone and went to ESPN's site for stats. Unfortunately it breaks it down into groups like which game, which team, which category (rushing, passing, receiving, etc) and then it finally shows you some stats. So if I wanted to see Edgerrin James' stats for example, I'd have to go to the Cardinals vs. Whoever game, then pick the Cardinals, then pick the category of rushing, then pick the player. So it requires alot of browsing and if your phone is slow like mine it's almost not worth it. By the time you finally get the stats you want, they're probably outdated if the game's still going. You can check end game stats that way though.
