The 6-foot-4, 225-pound senior point guard had led the Tigers to a 30-1 record and a berth in the Class 4A Super-Sectional at the time of his selection. Smith averaged 22.2 points, 8.6 assists, 8.3 rebounds and 2.1 steals through 31 games. He had recorded 14 double-doubles and two triple-doubles, and poured in 45 points to go with 13 rebounds in an 81-59 win over Danville High in the sectional final. The MVP of three in-season tournaments this season, Smith was a 2016 St. Louis Post-Dispatch All-Metro honoree and earned 2016 Belleville News Democrat First Team recognition.
Smith has maintained a 3.24 GPA in the classroom and represents one of the state's top academic candidates in meeting the Gatorade award's broad criteria. He remains undecided upon a collegiate destination.
A member of his school's Fellowship of Christian Athletes chapter, Smith has volunteered locally as a youth basketball and baseball coach. "Mark has been great this year. He has improved and elevated his game so much," said Rick Gibson, head coach of O'Fallon High. "He is such a strong and powerful guard that he is hard to contain. He gets to the basket so easily and is really explosive in and around the basket."
