Explanation Burden 6/10 — Anomalous. Mechanism Complexity 2. Closure Deficit 4.
How to read this Case: The factual account and sources establish what happened. The Archive assessment states the Desk's synthesis. The neutral explanation gives the best ordinary account and is the baseline for Closure Deficit; it does not withdraw the assessment.
Factual account
On September 12, 2010, the Detroit Lions opened the regular season against the Chicago Bears at Soldier Field. Trailing 19–14 with approximately 24 seconds remaining, quarterback Shaun Hill threw a 25-yard pass to wide receiver Calvin Johnson in the end zone. Johnson leapt over a defender, caught the football, established possession with both feet on the ground inbounds, and contacted the turf with his left hand and body. As he pushed off the ground to celebrate, the ball came loose on the turf. Referee Gene Steratore and his officiating crew ruled the pass incomplete. Steratore explained in the pool report that because Johnson was going to the ground to make the catch, he was required to maintain continuous control of the ball throughout the entire contact with the ground. The ruling stood, and Chicago held on to win 19–14.
Archive assessment
Calvin Johnson appeared to catch the ball. Under the rule, he had not finished catching it. The dispute turns on the gap between an ordinary catch and the league’s definition of a completed one.
Neutral explanation
The incomplete pass ruling matched the going-to-ground standard articulated by referee Gene Steratore in his postgame pool explanation. While Johnson established both feet inbounds, Steratore explained that going to the ground required maintaining possession throughout contact with the turf. The play became a central reference point in subsequent league and public debates surrounding catch definitions.
Verification note
Institutional recaps and contemporaneous pool reporting from referee Gene Steratore support the play sequence with 24 seconds remaining. The accepted evidence grade is C because the specific 2010 rulebook text was not independently opened.
