I found this quote from Bill Belichick on 20Secondtimeout today. "Any coach, whether it's high school, college, pro, whatever it is, any coach's job is to try to maximize the potential and the ability that a player has. I don't really understand the word overachiever. I don't really know what that means. To me, what everybody is trying to do is do their best. If somebody is doing their best, I don't see why that really should be regarded as something that they shouldn't be able to achieve. Frankly, that's what they should be able to achieve. It's the ones that don't, to a degree, nobody is ever perfect, so in a way everybody is an underachiever, even some of the highest achievers. Every quarterback has thrown an interception. Every running back has fumbled. Every receiver has dropped a pass. So, it's never going to be perfect. But I really think that’s a misnomer. I think what a coach tries to do is maximize the performance of his players within the team context. That's really what it's about. Anytime you have an offensive line, again, the context there is also of the entire unit. One guy could block great, but if it’s not coordinated and consistent with the other guys, then you’re not going to have any production and it isn’t going to be any good. All five guys have to function as a unit and function as one. That's where your production of that unit comes from."
David Friedman the owner of 20Secondtimeout had this to say about it. “As Coach Belichick notes, even the greatest players underachieve sometimes. So, in a sense, the job of a coach is to minimize the instances when this occurs. In that context, ESPN analyst Greg Anthony's repeated assertion about Lakers Coach Phil Jackson is very interesting. Anthony has predicted (as have I) that the Lakers will make the playoffs this year, noting that wherever Jackson has coached you rarely see players underachieving; Jackson seems to find a way to get the most out of everyone, from the superstars to the 12th man. If the Lakers do in fact make it to the playoffs, some will say that the team has overachieved, but Belichick, Jackson and Anthony will understand that what actually happened is that the team found a way to minimize underachievement and to get each player to perform at or close to his peak level for as long a period of time as possible."
I agree with the statement that Belichick made and I also agree with what Friedman is saying. I think Belichick is one of the best coaches able to get his players to achieve what needs to be done. Some coaches have the ability to get their team ready and motivated and they are usually the coaches that you see in the playoffs and winning the championships.
