We'll disagree. The calling official here has an unobstructed look directly in on this contact and drops his hat indicating that he's got the receiver OB. The call is his judgment and his judgment alone here and it's obvious that he ruled that the contact here was enough to be considered a "force out". That's his call to make. The act of "Simply touching the receiver" as the receiver is changing direction and turning up field may well have been more than enough to cause the alteration of path that resulted in the OB and hat down.
The rule book and case book are mostly silent on what "due to contact" actually means, although a case play uses the phrase "blocked out" when discussing how a receiver went OOB.
The replay case book extensively uses the phrase "forced out" and it is also used in the mechanics manual. Common sense dictates that being forced out actually requires "force". It is hard to imagine a simple touch ever being consider equivalent to "blocked out" or "forced out".
The replay case book also states contact must be "clear and overt" for replay to create a foul for illegally touching a pass.
The receiver in this play was not "forced out", he was not "blocked out", nor was the contact "clear and overt". If the SJ ruled such, he was in error. I've watched the play in it's entirety and there was never an announcement that the ruling on the field was that the "receiver was forced out" as required when it occurs. Based on all the announcements, we really cannot be certain what was ruled on the field. After review, the Referee simply stated the ruling of catch was confirmed. Nothing about the receiver having been out of bounds.
Also, Bill Lemonnier stated unequivocally in his commentary, the receiver went out on his own, which he did.
