He caught 12 passes last fall in a run-oriented scheme. Register says he took snaps on offense and defense, more on defense due to injuries that sidelined teammates.
Register sees himself as a likely receiver on the next level, which makes perfect sense with his frame and athleticism. He's the type of player that can do big things when he touches the pigskin.
He's also a standout for the Spartans' powerful hoops program. His older brother, Hayward Register, is a senior Ragin' Cajuns' basketball signee.
Hunter and Hayward helped Comeaux to an impressive 30-5 mark (15-0 in district), No. 3 playoff seed and deep playoff run on the hardwood.
The Spartans captured three postseason wins before getting eliminated in the semis by eventual state champ Scotlandville, 58-50.
Comeaux posted a 4-5 mark on the gridiron. The Spartans finished strong by winning three of four to close out the year. The sole loss during that span -- a 28-20 setback vs. Acadiana -- came against one of the state's best programs.
During a January interview, Register said LSU is his early leader and that he'd likely commit if the Tigers offered.
On film his leaping ability and soft hands are immediately evident. He adjusts to throws that are off-the-mark, whether it's going high to make the grab or diving to snatch the ball before it hits the turf.
On defense Register does make his share of plays. He shows a surprising burst at safety. For example, he reads screens well, hustling in a hurry to the line of scrimmage to make the tackle.
He doesn't tend to fall for head fakes and jukes from rushers and receivers - another testament to the sophomore's natural athletic ability and football intelligence.
Register is similar to another tall 2015 WR/DB - West Feliciana's Jazz Ferguson - in that his speed is deceptive. Register can run, as shown on a clip vs. state runner-up Barbe where he chases down a swift RB in the open field.
In addition to LSU and the hometown Cajuns, Register mentions Texas A&M and Missouri as schools of interest.
