Obstruction play

[Clark Kent]

I don't want to fill the posts with all these random plays by some fella that is still learning the game, but a friend asked me to post this one. So if you can tolerate one more play I enjoy your insight.

This is a typically play that I see often. The Defender (I feel) established LGP, however his knees may be slightly outside the "normal" stance or the shoulder width stance. The offensive player does what he can to avoid contact yet there is still contact. Is this one I should've passed on?
