Lord of the rings: Roy Williams showed off his hardware to Julius Randle, a top prospect in the class of 2013. ROBERT WILLETT

John Calipari is a difficult man to beat these days on the college basketball recruiting trail. If the Kentucky coach seems to be able to land any prospect he wants, well, there’s a reason for that. He usually does.

Which is maybe why North Carolina coach Roy Williams traveled to Texas with a bunch of jewelry.

According to USA Today, Calipari on Tuesday traveled to Plano, Texas to visit Julius Randle, a 6-foot-9 forward who some recruiting analysts believe is the best prospect in the class of 2013. During the visit, the newspaper reported, Calipari showed off the ring he won when Kentucky won the national championship back in April.

And yes, Randle was impressed, USA Today reported.

Not to be outdone, though, Williams packed 30 rings when he visited with Randle. There were the national championship rings, presumably, that he and the Tar Heels won in 2005 and 2009, and various rings from Final Fours and conference championships over the years.

About all the jewelry, Randle told USA Today this:

“When coach Williams opened the case you almost couldn't look directly in it for fear of going blind. It was crazy.”

Carolyn Kyles, Randle’s mother, was also apparently impressed by Williams’ hardware.

She told USA Today, “Yeah, coach Williams was ready for coach Cal with those rings. He got him there.”

But will Williams get Randle? Stay tuned …
