Why do so many people treat the two as being mutually exclusive? Just because Pops is a better coach than Doc doesn't take anything away from Doc. That doesn't make any sense.
Popovich is a 4 time NBA champ, excellent coach for schemes, drawing up plays, rotations and all his players seem to love and respect him. He has also had an excellent team at his disposal since 1996 starting with the Admiral and Duncan and moving on through until now with Duncan, Parker and Ginolbili. He has gotten the most out of his players usually, overcome injury plagued seasons, but also underachieved several times as well.
Doc has only 1 ring from the 2008 season, but thats really the first time he has had a team that was truly a serious contender. He is a players coach, manages personalities very well, gets extreme loyalty out of his guys, say what you will about his rotations and how much Thibs had to do with his defensive schemes, but at the end of the day he has put together a great system for his guys. He's come extremely close to at least 2 more rings and you could argue that injuries were his main downfall, but his teams have outperformed their expectations (see last year's playoffs) and also underperformed as well.
Those are two amazing resumes if you ask me. Pops obviously has the edge based on rings and in my opinion overall coaching ability, but Doc's done great things as well.
There are very few teams and fan bases out there that wouldn't jump at the chance to have Doc as their coach. To say he is anything other than one of the top coaches in the league is, in my opinion, ridiculous. Yes Pops is better, of course he is, he is the best coach in the league, but why would that make Doc any less of a coach?
