AEW star Max Caster has just claimed that a certain former WWE tag team has not been a great signing for the promotion despite their popularity. The tag team in question would be MxM Collection.The duo, which consists of Mansoor and Mason Madden, were previously part of the Maximum Male Models in WWE, along with LA Knight and Maxxine Dupri. However, they were released from the company back in September last year. They made their AEW debuts back in July and have kept the gimmick they had with the Stamford-based promotion.On X/Twitter, a user talked about how any doubts he had about MxM Collection when they were signed to the company have since disappeared. Max Caster replied to the post and had a different opinion, as he called them a horrible signing by AEW."Horrible signing tbh," Caster claimed.It is interesting to note that MxM Collection and The Acclaimed have run into each other backstage a couple of times, and there seems to be a little animosity between them.Mansoor made a diss track toward Max Caster the moment he signed with AEWMax Caster has been known for his raps during his entrances where he insults his opponents. However, this hasn't been a regular occurrence lately, even now with Billy Gunn rejoining The Acclaimed.Back in July, it was announced that MxM Collection had signed an AEW/ROH contract, which now meant that they were set to appear for both promotions. Caster immediately replied to these reports as he claimed that no one wanted them.Mansoor had an interesting response to him, as he made a short diss track for Caster. He was using his gimmick against him.See the video below.These two teams have yet to clash in a tag team match, but with some animosity continuing to brew, this may happen very soon.
