With the recent news that St. Louis Cardinals manager Tony LaRussa and outfielder Juan Encarnacion are not happy with one another, it calls to mind some of the great feuds between players and the men in charge of leading them.

- Bobby Knight vs. Neil Reed: During a 1997 basketball practice at Indiana, Knight choked Reed, an incident that was caught on videotape. Knight denied the incident, and in an interview with HBO's Real Sports said, "I don't remember that. I am sure that I have with kids. I will tell you this: There isn't anything that I have done with one kid that I haven't done with a lot of other kids. I have no apologies to make whatsoever for anything that I have done in an attempt to motivate kids."

- Brett Hull vs. Mike Keenan: When Keenan was hired as coach of the St. Louis Blues in 1994, Hull didn't like the idea then, saying, "I find it hard to believe that my personality and his are going to get along too well." Boy, was he right. The two never got along during their time together in St. Louis, and publicly feuded with each other throughout Keenan's tenure. The feud has never simmered. In fact, last winter, Hull had this to say about Keenan: "He's a bad human. He's the NHL's version of Adolf Hitler. He did more bad things to good people than anyone."

- Oregon Women's Basketball coach Jody Runge vs. entire team: In 2001, Runge "resigned" after eight players on the team complained about her coaching manner, and how her communication methods. The eight members met with Oregon Athletic Director Bill Moos, who hired an outside firm to investigate. Soon after, Runge was gone.

- Danny Ainge vs. Robert Horry: Ainge was head coach of the Phoenix Suns, and Horry a star player. After being taken out of a game in 1997, Horry threw a towel in Ainge's face. He was suspended two games and later traded to the Lakers.

- Keyshawn Johnson vs. Jon Gruden: Unhappy with not getting the damn ball enough, Johnson famously screamed at Gruden in 2003 during a Monday Night Football game. Eventually, Tampa Bay deactivated Johnson in the middle of the season, citing his behavior as a distraction to the team. Afterwards, Johnson told ESPN, "I was never Gruden's guy. He never liked me. I told him I'd rather retire than play for him in 2004."

- Billy Martin vs. Reggie Jackson: Probably the most famous of player/coach conflicts, the two Yankees really went at it in Fenway Park in 1977. When Martin took Jackson out of the game for failing to hustle, the two famously went at it in the dugout. When Martin left the Yankees after the 1978 season, he called Jackson, "a born liar."

- Rob Dibble vs. Lou Piniella: In 1992, Piniella and Dibble literally started to fight in the clubhouse after a game. At issue was Dibble indicating Piniella was less than truthful with the flame throwing reliever.

- Latrell Sprewell vs. P.J. Carlesimo: When the two were in Golden State together, Sprewell became infamous for choking his coach at a practice in 1997. After leaving that practice, Spree returned, this time throwing punches at Carlesimo. The two had been bickering for most of the season, and Sprewell never played for the Warriors again. His contract was voided, and he was suspended for the remainder of the season.
