Mateos had been watching Williamson's viral dunk highlights on YouTube, and that's all he needed to see before he found his number and picked up the phone.
Let that be proof: Duke's season is just starting, and the Blue Devils' freshmen have already arrived.
According to Duke officials, the team's Instagram videos during the first week of the season were viewed more than 2 million times - more than fellow blueblood programs Kentucky (412,000) and North Carolina (172,000). Williamson is not just scoring, but at a super-efficient clip.
For the first time this season, and for the first time ever for the freshmen that heavily populate the Duke basketball roster, the No. 1 in the nation tag was worn by the team as it hosted Eastern Michigan on Wednesday.
Barrett and Tre Jones dished out a combined 14 assists to three turnovers. "More than how high he jumps, is his incredible body control". Duke won the bidding war over in state SC and nearby North Carolina.
Williamson is the ideal example of why the National Basketball Association rule prohibiting high school players from entering the National Basketball Association. Here are some of the best shots of Zion in mid-flight from early in the season.
Ireland were 'too good', admits New Zealand skipper
Captain Kieran Read believes his All Blacks will need to find a new gear to beat Ireland at Lansdowne Road on Saturday. Sexton nailed the conversion to make it a 10-point game.
The One-and-Done rule will not be around much longer.
Despite never playing tight end in high school.
Eric Mateos, the former tight ends coach at Louisiana State University (and now the offensive line coach at Texas State), spoke to ESPN recently and revealed that he was so impressed with Williamson's athleticism in 2016 that he offered him a football scholarship with barely a second thought.
Mateos said he never heard back from Williamson and that Orgeron likely never even knew about the offer.
"This is a team, and there are other players - there are upperclassmen, and they lead us, because they've been through this", said the 6-foot-7, 285-pound Williamson who wows fans with his athletic ability and acrobatic dunks. "A Julius Peppers-type of freak". The pass was high, but Williamson still corralled it; then he slammed home a two-handed dunk that sent Cameron Indoor Stadium into a chaos, with guard Alex O'Connell simply shrugging his shoulders in disbelief as he made his way back down court.
