The Reds lost 2-0 at Crew Stadium just a week after performing at their very best with a 3-1 win over Canadian rivals Vancouver Whitecaps.
TFC conceded goals to Justin Meram and Kei Kamara after Justin Morrow was sent off on the stroke of half-time but it was the overall showing which really resonated with captain Bradley.
"The biggest disappointment is not [the red card]," Bradley said.
"It's just that now even with that in the second half I still felt that were going to be able to control things in a smart way and still find our chances to play and get opportunities of our own.
"I don't think, in the decisive moments in the second half, at both ends, that we were good enough."
