I think Dave will be in a better mood when AEW gets off the ground. It's already got Vince worried and ROH is locking down talent.I think a lot of people have that impression of him because the only things of him that people put up on YT are him going off on WWE (or sorry, "SHOOTS HARD!!") or verbally dressing down TNA. He's definitely a weird dude but he's definitely not angry all the time. If you listen to him talk about stuff he actually likes (Takeover or Wrestle Kingdom for instance), it can be a lot of fun to hear him break down what parts of a match really work.
I think Dave is just very frustrated with WWE these days, because their product is regularly so fucking bad but their roster is the best it's ever been.
Speaking of Meltzer, JBL is having some kinda meltdown
And Meltzer's response is pretty great.
