Interesting perspective.
I've always thought there aren't many folks who don't "look like" wrestlers. You have so many heights, weights, shapes and sizes. Dan Spiveys to Dusty Rhodes to Ivan Putskis to Sal E Grazianos to Road Warriors to Playboy Buddy Roses, Goldbergs, Giants, and Rey Mysterios.
I don't think Mysterio could bodyslam Big Show, but that doesn't make him not look like a wrestler.
Now, if your point is that his appearance is generic (generic tights, generic physique, haircut, relatively bland promo style), I can give you that. Again, your taste is your taste. I've always hoped for a few folks to come into wrestling to make it look like a *sport* again. I know it's not, but I'm ready to suspend my disbelief. Not everyone needs pyro, or shit all over their tights, or "HOW D'YA LIKE ME NOW!" rockin' entrance themes. If Danielson's character is "I'm here, I'm a wrestler and I wrestle," that makes him stand out compared to catchphrases and whatnot. Danielson's major weakness on NXT was during his promo, as he lacked the projection needed to engage with a crowd of 10,000 or so. That's an acting thing, not a wrestling thing. But still vital in this era of wrestling.
I see different in him. And I like it. I see him on one side of the spectrum of "You need charisma, and a look, and a character, and whatever else" to be a wrestler. And I see Darren Young waaaaayyy on the other side of the spectrum, going so far in one direction so as to be a magnificent bastardization of what a 'sportz entertainer' should be.
But I'm old-timey like that. I wish for more in-ring stuff every week. I hate 15-minute segments with full entrances, lines forced out like play-doh through the fun factory, stipulations for main events that never have full resolutions, villainous managers/owners (especially this: Austin/McMahon made some sense, but 10 years of vengeful/manipulative GMs and McMahons is redundant and boring, and the whole premise - I'm deliberately sabotaging the career of my biggest company cash cow - is absolutely preposterous). I want to see a no-commercial 8-10 minute match that tells a story. I rarely ever get that on Raw.
Truth be told I sometimes think Rob Van Dam ruined *everything* about modern wrestling matches. But I'll save that spiel for another day.
