Selection Sunday is less than two months away, which means it’s officially Bracketology season — the time the sport begins to take center stage. It’s been a strange year up to this point. Final Four favorites have scuffled. Forgotten programs have thrived. One freshman — and not the one most experts predicted — has emerged as the sport’s big, must-watch star. Below are three major storylines we’re watching as the season revs up: ’Homa hero Pick a stat, almost any stat, when it comes to Trae Young, and it’s impressive. There are his 30.1 points per game and 9.9 assists — both No. 1 in the country by a wide margin — 40 percent 3-point shooting, and 83 percent clip from the free-throw line. He equaled the NCAA record with 22 assists in a single game. All are impressive for a player of any age, but even more so for a freshman. But the number 14 — in wins — is what stands out the most. It’s three more than fourth-ranked Oklahoma produced all of last year with a similar roster and identical coaching staff. The only change is fellow freshman forward Brady Manek, third on the team in scoring and rebounding. Young isn’t just putting up gaudy numbers while becoming college basketball’s biggest star, he’s doing so in the process of winning immediately in arguably the best conference in the country for a team that was an afterthought entering the season.
