No one seems to have a clear understanding of what the targeting rule is, including the officials in the College Football Playoff National Championship Game.

Alabama vs. Clemson: National Championship game gets off to an insane start

Alabama linebacker Mack Wilson appeared to strike Clemson quarterback Trevor Lawrence helmet-to-helmet during a zone read run in the second quarter. A slow-motion replay shows Wilson squatting to unload a tackle as Lawrence lowered his head.

The crown of Wilson's helmet crashed directly into the top of Lawrence's helmet. If the officials had ruled that targeting, Wilson would have been disqualified from the remainder of the game, but no flag was thrown.

Lawrence did not appear rattled by the hit. He and Clemson proceeded to a touchdown.
