Miami Dolphins head coach Joe Philbin has revealed that he uses both practice and game performances to decide who to play on matchday.
Philbin said that while there are more snaps per session in training, how a player reacts to a match situation is equally important.
"We look at the total picture. We've roughly averaged 115 snaps a day out here on a typical day," he told the club's official website.
"A particular player may only get 15 in a game. He may get 30 in a game. I think we look at the whole spectrum of things, and hopefully by the time the end of next week rolls around we've got enough information to make good decisions."
Dolphins face Tampa Bay Buccaneers in a pre-season match on Saturday.
