Is it possible all of them were wasting their time? Might they have been just as productive hanging out by the hotel pool or trying to beat the dealer to 21 at the high-stakes blackjack tables?
Maybe Melo will choose one of their colleges. Maybe he won't. But what those coaches have in common—and share with others loaded for pursuit of the 2010 NCAA championship—is that one or more key players on their current rosters were the product of little more than providence.
So why did he end up with the Mountaineers?
"My effervescent personality," Huggins said, wryly. "Please put that in bold letters, would you?"
Huggins acknowledges good fortune played a huge role in Ebanks winding up at WVU. If the Mountaineers didn't have an opening when he became available, they might not have been able to take him.
Huggins acknowledges, "You almost want to leave a scholarship open to be ready for what happens in the spring."
A half-dozen years ago, all these coaches would have faced dramatically different circumstances this season. It was extremely uncommon then for a player to be released from a letter of intent because the coach he signed to play for was fired -- or hired by another program.
The letter of intent now has become so easy to escape there is no real disadvantage for prospects to sign in November. A player can get a guaranteed spot at his first choice, stop all the recruiting calls and hassle. And if a coaching change alters the circumstances in a way he does not like, he merely can request a release and go shopping again, in a buyer's market.
The nation grieved for those hurt, killed and affected by the Boston Marathon bombings. After one of the suspects was caught on Friday — following a day-long lockdown and manhunt — sports returned to Boston over the weekend.
Sometimes, good luck with such a recruit is the residue of design. The Jayhawks worked to get Taylor in the fall of 2007, did the home visit and all of that, but they held him off while waiting to see if they could fill that position with Willie Warren, a more highly rated prospect. By the time Warren chose Oklahoma, Taylor had already pledged himself to Marquette.
"The harder you work, sometimes, the less productive you are," Self said, chuckling. "It's true. I used to worry about everything. I don't think I worry as much now, because the rules have changed so much."
So what are all of these guys doing out here, getting in and out of sizzling rental cars, fighting Vegas' unyielding traffic and torturing their backs on metal bleachers?
The simple truth is they need to see who can play, and who can't. Because next spring, some of these players almost certainly will be "free agents," and most every college program will have vacancies they hope to fill.
