In a Super Bowl that saw 1,151 total yards, 74 points in a 143 plays, perhaps the one play that proved to be the most important for the Eagles came late in the second quarter. With 38 seconds to go in the first half, and the Eagles leading 15-12 and facing a 4th and goal from the Patriots' 2-yard line, coach Doug Pederson didn't turtle up. Instead of settling for an easy field goal, he called this:

First, that takes guts. Second, Pederson dialed up that play minutes after Tom Brady flubbed his chance at big reception:

But here's the thing, should the Eagles have been flagged for illegal formation on Foles' touchdown grab? Because former Patriots player Matt Chatham tweeted this shortly afterwards:

Given that the Eagles won by eight points, that would be a huge missed call.

But a league source tells Pro Football Talk that the NFL views the play as a judgment call, not one that is clearly right or wrong. More from PFT: 

The question is whether the wide receiver was on the line of scrimmage, in which case the formation was legal, or behind the line of scrimmage, in which case the Eagles only had six players on the line and were in an illegal formation. The official thought the wide receiver was lined up close enough on the line to be covering the right tackle, and as a result the league doesn't believe the Eagles got the benefit of a bad call.

Credit to the officials for not making the Super Bowl a referendum on controversial calls. Foles' touchdown grab is one example, and there were at least two others: Corey Clement's 3rd quarter touchdown catch, and Zach Ertz's game-winning touchdown catch with just over two minutes to go

NFL Commissioner Roger Goodell is widely criticized, and sometimes deservedly so, but he was exactly right to express concerns about the catch rule and make a concerted effort to fix it. Super Bowl LII was a glimpse into a game that was about the two teams and not arcane rules that are almost impossible to enforce.
