Some of the most successful coaches in college basketball are fiery men.
They are intense individuals, focused and determined about their craft.
Fiery doesn't necessarily mean being physically violent or constantly vicious.
But the following college hoops leaders do not lack spirit or enthusiasm.
Here are the 10 most fiery coaches in college basketball.
Buzz Williams is a passionate sideline leader who has had great success as Marquette's head basketball coach.
Now in his fifth year at the MU helm, the Warriors have gone 113-50 and made it to the NCAA Tournament every season.
Looks like Buzz has some hops!
Coach K didn't become the all-time career wins leader (949-293 and counting) by being indifferent and apathetic.
And the fire is definitely still burning. Sure, when Krzyzewski gets into a press conference, he is normally under control.
But several times this year, the television cameras have captured K being very animated on the sidelines. We even witnessed an awkward Coach K chest bump.
I love it.
Over the years, Tim Floyd's teams have been gritty, grind-it-out squads because Floyd is a tenacious, hard-nosed coach.
His UTEP teams, like those at USC, Iowa State and New Orleans, are defensively oriented and win games by applying aggressive pressure.
Arizona's head coach Sean Miller is no hothead, but he is intense.
Because he has taken a single-minded approach to reestablishing the U of A program, the Wildcats are back in the top tier of college basketball in a relatively short amount of time.
The Cats have gone 89-39 under Miller's persistent leadership.
Florida's Billy Donovan has had huge success over his seventeen seasons in Gainesville, winning over 400 games and two NCAA Championships.
Teams reflect the personality of their coach, and that's why the Gators' basketball program plays with an edgy relentlessness.
Tom Izzo's Michigan State teams are tough because he is tough-minded and determined.
Izzo is in his eighteenth season at MSU. On his watch, the Spartans are 433-173 and have gone to six Final Fours, winning one national championship in 2000.
One reason Izzo does such a great job of developing talent and getting the most from his players is that he constantly challenges them to keep improving.
If you've ever seen Shaka Smart in action, you know that it is no coincidence that VCU's exhausting defense is known as "Havoc."
Because Smart is 120 percent passion and enthusiasm, his Rams totally sell out. Under Smart's leadership, Virginia Commonwealth has gone 101-31 and made a trip to the 2011 Final Four.
If you spend any time around this young coach, he is likely to pass along something from his vast collection of quotes.
Bob Huggins has always been a hold-nothing-back kind of coach.
Ironically nicknamed "Huggy Bear," Huggins' straightforward, blunt approach has translated into over 700 career wins.
To say that Wisconsin's Bo Ryan is fiery is like saying Bill Gates is kind of wealthy.
Ryan's forceful style consistently creates teams that play tough, disciplined basketball and can compete regardless of the talent level on the squad.
I don't want South Carolina's Frank Martin ever to be mad at me.
Just watching him on the sidelines can scare the bravest of souls.
Before being hired as the Kansas State head coach, he served as an assistant under Bob Huggins for two years.
Can you even imagine the intensity level of practices or the explosiveness of locker room speeches when one of the Huggins/Martin teams were not playing up to par?
In five years at K-State, Martin posted a 117-54 record. And in this year, Martin's first at South Carolina, the Gamecocks have already won two more games than the team won all last season.
