Here's one thing I'm struggling with about Kelly's system...he is known for running very fast, intense practices. But instead of practicing in Oregon or in an indoor facility, he is doing it outdoors in Spartanburg and Charlotte. And the players won't be 18 to 22, they'll be 24 to 34 year old men. NFL players are stronger and more bulked up than college kids. Are they going to be able to run that system? And if not, what does Kelly then bring to the table that other coaches don't.
I'm not anti-Kelly, but color me less than completely sold that he'll translate to the pros.
Two campers come upon an angry bear. The first says, "I'm glad I wore my running shoes." The second says, "you can't outrun the bear." The first says, "I don't have to outrun the bear, I just have to outrun you."
point is...he doesn't have to have the guys he coaches at the pros run as fast as they do in college or for as long. he just has to get their endurance up to outlast the guys they face every week.
his won't be the first hurry up/no huddle offense in the league. other teams have done it for years. the broncos (in denver with thin air) and the pats are doing it.
he'll adjust to what they can do, they'll adjust to what he wants to do.
anyway....i think that the players will be more able to work at that fast pace than what you realize. some will be weeded out, bit these are professionals. they'll be able to get with the program. if they can't do we really need them around?
