If i were you i would of bet atleast the ammount of the pot. You have 2nd best hand and too many people in it to be comfortable, even if they fold you still get a few chips to sit on still early in the tourney. I suspect he was scooping blinds while somewhat low stacked. What kind of hands was he showing down, solid better, a little more info on this "ed" guy might help a little. Anywho,even early in these tourneys people like to go all in with an AK AQ so even if u did call you woulda had him down to close to 20%. sorry if sentence structure and spelling are not great, im tired and hope i helped with my input.
