Backstretch move: Logano tried to fake out Matt, who went a bit low and opened the high lane. Logano went there and Kenseth pulled the block. That's two moves, even though NASCAR doesn't have that 1 change of lane per straight, which in my book is not cool. Joey gave Matt a bump and life goes on.
Example of this kind of move: Edwards vs. Keselowski @ Talladega 2009. Compare both. Same moves, different ending though.
Tri oval and Turn 1 move: Both cars came across 3 lapped cars. Matt tried to go under the white lane, and for some odd reason lost some speed, which made Joey close on him even faster. Logano HAD to go high, there wasn't any other lane available. Matt, wanting to get the W and his ticket to the next round, went to block. They went high as they could, and then Joey hit the wall. Considerably hard. It was the second block in less than 7 laps, so he just gave Kenseth another bump and spun him around. Simple. There was no room on the inside of Kenseth, since the other two slow cars were there. Logano could've waited, but at the same time it's not fun to get blocked twice and even pushed to the wall. Ok, Logano could've avoided the wall hit by slowing down, but he didn't.
I'm still trying to find a way on how Logano was wrong this. You block, expect the bumper. It's simple as that. I don't like Joey, but I'm siding with him.
