The Dynamo were beaten 1-0 after Landon Donovan supplied the only goal of the contest at The Home Depot Center and Kinnear was critical of his side's inability to really trouble the Galaxy defence.
"We were a little bit slow, but we were getting it forward," Kinnear said in the postgame press conference. "We just weren't clearing our lines fast enough for me.
"We had one or two good balls in the box. I did think we played a little bit better in the second half than we did in the first, but you still need to score a goal. When we got into those good areas, our delivery was off to not put them under pressure.
"In that sense, we kind of let them off the hook. You want to put good pressure on them so you kind of pin them in a little bit. It took one goal to win it, which sometimes that's what finals are all about.
"Even on the set pieces we had we were just off," Kinnear added. "It wasn't one particular person. You have a corner kick or free kick, you want to put them under pressure and I don't think we did that enough tonight."
