I don't think he wants to give Day a chance to make it look close, imagine him having a close battle with a nikka who trolled for so long
I 100% believe Lux would be that petty, it's Harlem
I'll take it further then that.
I don't think Lux has any interest on battling a "pen" guy (JC, Chilla, Danny Myers, etc).
His actions show it. JC elevated himself at one point where the battle made sense. Lux just waited it out, because JC was eventually going to cool off due to the large volume of battles he takes.
However, he may have to “step down” and battle one of these guys at some point due to necessity. These guys are slowly running out of top tier opponents.
I bet his shortlist of opponents are probably guys like Hitman and Easy, which align with how he selects his opponents. Those would be big battles.
