Saint Louis assistant Jim Whitesell had heard good things about the six-foot point guard and head coach Rick Majerus did his homework to make sure that he was a player the Billikens could use in their system.
According to the elder McBroom, Majerus, who spent much of the morning speaking with Allen, inquired with MAC coaches, NBA scouts, and watching copious Synergy tape on Austin from last season.
"It's a great opportunity for [Austin]," Allen said. "Primarily because of Coach Majerus. . .Austin was his first choice."
The family was clearly impressed with Majerus' past in terms of developing players on-and-off the court.
McBroom averaged 10.9 points per game for the Chippewas, but ultimately decided that heading elsewhere would be the best choice for his goal of playing beyond college.
"Everybody I talked to, every coach I talked to, and everybody I know that knows the game, could do nothing but speak extremely high of Coach Majerus," McBroom said. "We know what a great coach he is and what a great teacher of the game he is."
McBroom also cited the fact that the Atlantic 10 is a step-up from the MAC in terms of competition level and talent across the board as being a reason for the new destination.
McBroom mentioned seeing the Billikens beat Memphis in the NCAA Tournament and come within a few plays of downing top-seeded Michigan State.
The campus and amenities were not forgotten, either.
"The school is beautiful," McBroom said. "Austin loved everything. He loved the players, the coaches, the facilities. . .They draw almost 10,000 people for every game which is awesome. That's something new for Austin."
When it came down to it, though, there was a clear reason why this decision was made.
We know [Majerus] is an old-school coach, but that's a good thing. That doesn't scare Austin. Austin wants to be pushed," McBroom said. "Obviously Rick Majerus was the main reason for choosing Saint Louis."
During the upcoming year when Austin will sit out under NCAA rules, he'll be working on a couple different things.
"Coach Rick said offensively he's really strong," McBroom said. "He said he can flat-out shoot and it's hard to find point guards that can knock down the open three. . .but he wants to take Austin from a two-speed player to a three and four speed player. Also with the strength and conditioning program that Saint Louis has, he'll really be working on just getting stronger and finishing more around the basket."
His defense and off-the-ball defense are also areas of improvement needed in order to see playing time.
"He has an extremely quick first step," McBroom said. "There's no reason why he can't be a great defender. Majerus said when he watched him on film that when he slides his feet, sometimes they come together. There are just little things he needs to tweak."
Despite being a California native, Austin wasn't worried about the distance. The style of play and coach were enough to outweigh any homesickness that he may have.
"After going on the visit and talking with the players, and knowing that Majerus likes to play with two guards," McBroom said. "That's when Austin is at his best.
McBroom said that Austin really enjoyed the current players on the team and figured St. Louis would be a great home for the rest of his career.
Majerus will be out to California in mid-June to visit with the family and some of Austin's former coaches in high school and AAU.
"Our biggest thing is we hope Coach is there the whole time Austin is there," McBroom said. "He's the main reason to go there."
