Fletcher, who is entering his 16th season in the NFL, said that Kelly's style means that communication in the team on game day will be much clearer.
"This is a unique style of fast-paced offense because it's no-huddle, but it's also a spread zone-read-type offense, things like that," the Kansas City Star quotes Fletcher as saying.
"It's definitely a situation where we're going to have to have great communication come Monday night. Obviously the communication is going to have to be a lot faster."
Fletcher has played for the Skins since 2007.
