Does he get to go Jar Kai? Because that does help defend against 2 opponents simultaneously IMO.
Anyway ROTS Kenobi is capable of winning, seeing as what he did against Maul + Opress. But I wouldn't put money on him doing it consistently. Seen as Kenobi has plenty of low showings as well.

He doesn't get jar Kai due to there not being a second saber in the arena.
