Posted this in the Agents of Shield thread, but I figured it was worth bringing up again here if it hasn't already.
Crusher Creel, the guy Jack Murdock whoops, later shows up in Agents of Shield as Absorbing Man. That's cool, but what stood out to me in particular was a potential age discrepancy. Brian Patrick Wade, who played Absorbing Man, is 36 years old. Charlie Cox is 32, so only 4 years younger. I'm assuming Matt Murdock is still in his mid-late twenties since he is only just beginning to practice as a lawyer. Assuming Wade plays an Absorbing Man in his 40s, it should be fine, I guess. We can probably also assume an ageing Battlin' Jack was fighting a significantly younger Creel, I guess.
