I worry that him being head Cool Badass Superspy Agent of Team Cool Badass Superspy Agents might ruin the "ordinary" quality that Agent Coulson has that makes him, ironically, extraordinary in this universe.
If there's one thing that is apparent in the pilot, it's that he's not a badass (at least not in the vein of Fury). He's more in the mold of the bureaucrat with a sense of humor and purpose. The badass is covered in the pair of the combat specialists May and Ward, sufficiently diluted with their lack of interpersonal skills.
Also, my money is on Colson being a clone with memory imprints.
On a side note: the episode plot struck me as something more suited for a 4th or 5th episode rather than a pilot (obvious longer-term antagonist, clear concern about the true nature of the organization, a "John Q. Public" antagonist, kids, etc.). Pilots for sci-fi/action shows tend to be more focused on building the individual characters of the team, which this does, and explain how they got mushed together. The plot for the pilot is pretty much "here's the case," and didn't require the building of the team for it.
But not every launch can be perfect, and this one was serviceable. I'll totally-not-pirate the show and watch as soon as it's uploaded.
