Not really sure why you felt the need to post a screen grab. I am not disagreeing with what happened, I am just disagreeing that this is a big enough deal to be harping on it like you are. Yeah, he may have been able to get there first and poked it to Seth. Or he could have gotten smoked on the play. Or the Philly F could have anticipated he was going to poke it around the boards and gotten it before Seth. Instead, Korchinski allowed the F to get there first and pinned him, which as you said worked out fine because he had support.
Again, you seem to have this weird fascination with his physicality. If I remember correctly you had the same issues with Vlasic last year.
