Seems interesting and Ollie was with him at OTE. Here's a scouting report:
Jaylen Martin
High activity point of attack defender who can score in bunches
Meet Jaylen Martin
RSCI’s (Recruiting Service Consensus Index) 210th ranked prospect spent the past season in the Overtime Elite League where he struggled managing just under 7 points a game on 50% true shooting. But, following an offseason of hard work Jaylen Martin has flourished into a highly efficient high scoring machine putting up gaudy numbers this season. In just 23 minutes a night through the OTE preseason and regular season Martin is currently averaging 17.7 points, 5.4 rebounds, and 2.7 steals a game on a ridiculously efficient 65.5 TS%.
