UNC's Roy Williams measures effort on scale from '0' to 'Tyler Hansbrough'

Any North Carolina players out to impress head coach Roy Williams with their effort have an enormous bar to reach.

Williams has been coaching for a minute, starting in 1988 at Kansas and moving on to North Carolina in 2003. He's seen some players in his time, and he's definitely had some gritty, tough, high-effort players suit up for him.

Of those, none measure up to Tyler Hansbrough, the standard-bearer for effort level on all Williams teams.

On Friday, Williams drew a scale on the team's whiteboard to measure each player's effort, with the scale starting at "zero" and ending at "5,000" with Hansbrough noted at that end of the scale.

Hansbrough, now with the Toronto Raptors, spent four seasons at Chapel Hill, making four All-ACC teams and three first-team All-American teams and being named the 2008 National college player of the year. While he didn't win the award in 2009, he won something bigger - the national championship.

The 6-foot-10 Hansbrough ranks 13th in all-time NCAA scoring and has countless iconic moments on his resume, enough that he's earned The Pscyho T Mix on YouTube:

When it comes to effort, it's tough to argue with Hansbrough being the scale against which all other players are measured. Good luck living up to it, Tar Heels.
