Matt Striker's not good enough to carry the HYPE but if he was with a team where everyone seems excited he wouldn't drag it down. I think if you wanna use Josh Matthews though you need someone who's really into it for an optimal team though. Don West is the only guy other than JR that still works and is alive unless you can get Tony Schiavone or Joey Styles (assuming they can still seem interested-- kinda doubt it especially in Schiavone's case) to announce somehow.
