Hi guys, I would like some football officials opinions on two plays from Monday night's Colts-Eagles game.

First play: TY Hilton holding/PI? This is the best video I could find:

Second play: LaRon Landry horsecollar on Darren Sproles? No video, just this picture:

I read the rule (Rule 12, Section 2, Article 15) but I'm not sure if I understand how it applies. It seems to suggest that pulling the jersey is also horsecollaring. How do you interpret the rule in regards to this play?
