TUSCALOOSA, Ala. — Collin Sexton is off to the NBA and Braxton Key has decided to pursue other ventures. Those subtractions leave Alabama basketball without its top two scorers from the past two years.

Last season, Sexton averaged a team-high 19.2 points and also led the team with 3.6 assists. Key finished with a disappointing 7.0 points and 5.3 rebounds per game but was coming off a freshman year that saw him average a team-leading 12 points and 5.7 rebounds.

So who will Alabama’s go-to guy be next season? Right now, that answer is somewhat of a mystery.

Donta Hall was second on the team in scoring with 10.6 points per game and will return for his senior season next year. However, the 6-foot-9 forward does most of his damage on dunks and baskets near the rim. Five-star guard John Petty is coming off an up-and-down freshman season in which he averaged 10.2 points and led the team with a 37.2 percentage from beyond the arc but faltered on the road.

Rising redshirt junior Dazon Ingram could step into a bigger role as could rising sophomore Herbert Jones. However, the player who has generated the most buzz this offseason hasn’t yet stepped on the court during a game for the Crimson Tide.

Tevin Mack will join Alabama’s active roster this season after sitting out last year following his transfer from Texas. The 6-foot-6 wing player led the Longhorns with 14.8 points per game and a 39.1 percentage from 3 during the 2016-17 season before being suspended indefinitely after 15 games.

After enrolling at Alabama last summer, Mack worked on the Crimson Tide’s scout team this past season, turning a few heads in the process.

“He was our best player at a lot of our practices,” Alabama head coach Avery Johnson said. “We want to see if that transfers to the game.”

While the former Rivals 100 recruit brings with him much anticipation, there’s a slight hesitation when projecting his impact on next year’s team. Much of that comes from the performance of former Ohio State transfer Daniel Giddens, who struggled in his first season at Alabama last year, averaging just 4.8 points and 2.5 rebounds per game while constantly finding his way into foul trouble.

Johnson acknowledged that concern but said Mack should have an easier transition than his 6-foot-11 teammate.

“I think it’s different for a wing player,” Johnson said. “Sometimes with big guys, their timing is off, maybe foul trouble, they’re out of position. But for wing players, I think they have a better opportunity to adapt and adjust quickly.

“You’ve got to remember, Tevin had two years of playing at Texas — even though the second year was cut short. But I think hard work this summer and coming early and staying late, I think he’ll have a better chance to adapt a lot earlier.”

The hope for Alabama is that Mack will not only be a solid performer but will also help his teammates reach new levels. Last season, Alabama finished No. 11 in the SEC, shooting just 32.4 percent from beyond the arc.

With Petty serving as the Crimson Tide’s only real threat from the outside, most opponents were able to find schemes to take the hot-shooting guard out of the game by forcing him into difficult shots on the perimeter. Mack’s presence from deep along with the return of senior forward Riley Norris, should not only help Alabama’s 3-point percentage but also clear up some better looks for Petty next season.

“He’s going to bring a lot,” Petty said of Mack. “I mean he’s a great outside shooter, and he’s a hard-hat guy just like Riley [Norris]. So, Coach Avery knows what he’s doing, he’s going to put all of our pieces and just make sure they work right together. We’re going to be pretty good.”
