Break it down to its simplest terms. The milestone is 20 wins over the course of 40 seasons. But reaching 800 career victories involves so much more. And it certainly isn't a simple task.

Add the pressure and stress of big-time Division I college basketball. Consider the money today's most successful coaches earn at younger and younger ages. Just think about coaching well past the age of retirement. It all prevents most coaches from even thinking about joining the likes of Dean Smith, Adolph Rupp, Jim Phelan and the soon-to-be the newest member of the 800-win club, Bob Knight.

The stamina needed year-in and year-out to maybe join Knight, who has 799 career wins in 37 seasons heading into Wednesday night's game against Nebraska, let alone pass him or the others ahead of him, is likely too much for coaches in today's high-pressure fishbowl of college basketball.

"I don't know if I can coach long enough to get there," said 52-year old Kansas coach Roy Williams, who just picked up win No. 400 last month. "I've coached for 15 years and I would have to coach another 15 at this pace to do that. I would be 67 if I coach another 15 years. I hope I'm on the first tee before then.

"It's mind-boggling what Bob Knight has done; what Pat Summit (at Tennessee) and Jody Conradt (at Texas) have done. I don't know if people could do that anymore, because there is too much stress and all the off court stuff that you have to deal with."

The common thread between the latest members of the 800 club is starting to X and O early. Knight, Summit and Conradt each began their coaching careers in their 20s. All have done a remarkable job at high-pressure jobs. Winning almost exclusively at one school is another aspect of reaching 800 wins that will be hard to match. Coaches don't stay at one school for 10 to 15 years, let alone 20 to 30.

"The fact that coach Knight got the bulk of his wins at one school is really amazing," Texas coach Rick Barnes said. "It's really hard to stay at one place. I wouldn't be surprised if I'm still coaching and he's getting 900. He has found a place where he's comfortable.

"But to get to that level, you've got to be at a school that can have basketball success. That's where Roy Williams is at Kansas. You can't get to 800 and be at a school that is fighting to get to 16, 17 or 18 wins. Coach Knight started out at Army, one of the toughest jobs in the country. He was able to win there, able to win at Indiana and stay in this for a long time. His longevity in the business is equally impressive."

This isn't to say Knight will be the last to reach 800 wins. There is a group of "old school" coaches who could reach the milestone over the next few years.

	... while Lute Olson doesn't see reaching the milestone at Arizona.

Former Illinois and present New Mexico State coach Lou Henson is at 755. Oklahoma State coach Eddie Sutton has 719 wins, gathering the majority of those at Arkansas and Kentucky before moving to Stillwater. Each are close enough by getting over 700 wins to where it's obtainable and certainly worth sticking around.

But, does Sutton think he has the stamina to get to 800? It would likely mean the 66-year-old would be closing in on 70 when No. 800 rolled around.

"I do today," Sutton said. "Whether I'll have it next week, I don't know. But I'm going to try."

When it comes to those still in the 600s, or the younger coaches piling up wins, coaches who are starting their careers in their mid-30s are already at a decided disadvantage. There simply may not be enough years to get to the magic number.

"I'm not sure you'll find very many coaches who will put in as many years as Bob and I have put in," said Sutton, who is in his 32nd season.

"Fewer coaches are going to get head coaching jobs in their 20s because schools want coaches with more experience," adds Barnes. "There is too much at stake for an athletic director to get to the NCAA Tournament. Schools have to be more selective than that."

Michigan State coach Tom Izzo has been to three Final Fours and won a national championship, but hasn't even cracked 200 career wins in seven-plus seasons. He's 48 years old and doesn't think coaches starting out in his era will get to 800 because there is too much parity in the sport, which means more hiring and firings.

Even the coaches who seem close enough to hit 800, like Arizona's Lute Olson (678), or those who seem like they would have the longevity like Stanford's Mike Montgomery (509), or those young enough to make a run like Florida's 37-year-old Billy Donovan, want no part of the chase.

"I had 17 years in this business before I got to Division I," Olson said. "I would need over 100 more. You can't predict health or anything else so it's doubtful (he could get to 800). The job is too year-round with the media and alumni demands. I'm not sure someone could stand 37 years of it the way things are going now."

Olson said he is convinced that former North Carolina coach Dean Smith, who leads all coaches with 879 career victories, would still be coaching if he didn't have to deal with today's demands of coaching off the court.

"It's harder for people to survive in coaching," Olson said. "But one thing about this is you don't lose for long."

	“	It's remarkable that Bobby Knight still has the same passion and energy for teaching as he did at a very young age. That's a very, very rare thing. I don't know if I would have the stamina to coach long enough to reach a milestone like that. ”

Montgomery points to the rising salaries in coaching as another detractor. If a coach is successful enough to think about milestones like 800, he's likely compensated well enough to give the chase a second thought. Why stay in a business with so much stress and demands so much time away from family?

And as for Montgomery, "I have no interest in that (800)."

However, if there is a thirty-something coach who is winning enough games and appears willing to stick around into his late 60s, it could be Donovan.

"It's remarkable that Bobby Knight still has the same passion and energy for teaching as he did at a very young age," Donovan said. "That's a very, very rare thing. I don't know if I would have the stamina to coach long enough to reach a milestone like that.

"I will coach as long as my passion for the sport is still as intense as it is now. I applaud the Dean Smiths, Bobby Knights and Coach K's of this profession who have been able to sustain the passion for our sport and sustain their level of success for so long.

"Even getting a coaching job in your 20s might not be enough. "You have to have a situation where you have the time to develop a program and have the passion to sustain it."

Twenty wins, 40 seasons ... think about it.
