Willie Mack, who'd be best known for his work with Californian independent promotion Pro Wrestling Guerrilla, sent out a tweet (see below) hinting at what could potentially be a Ring of Honor debut at their March 1st pay-per-view, the 13th Anniversary Show. Mack made headlines in recent months when he was signed by WWE, but then quickly released before he could ever compete for NXT.
The only name advertised for the 13th Anniversary Show not in a match is "Reborn" Matt Sydal.
I've seen some of Willie Mack's stuff, he puts on a solid show given the right booking, but then again so do a lot of people.. Would you be interested in seeing him with ROH after being dropped by WWE? For the right price I think he could be a pretty heavy contributor to the promotion.
