It was 8:27 p.m. Monday when the collision happened, and maybe a minute later when the ESPN cameras slowed the ominous violence Zapruder-style to reveal the worrisome angle Jaxson Dart’s knee took after he was mauled by a couple of onrushing Rams linebackers, Byron Young getting him high, Josaiah Stewart hitting him low. 

Hitting him in his knee. 

And the knee immediately looking … not quite right. 

For the next 18 hours, 10 minutes, those whose moods are dictated by the highs and lows of the New York Giants went through the real-time roller coaster that all such injuries in all sports bring now. You search for clues. Did one of the Giants trainers really whisper “four to six weeks” into John Harbaugh’s ear, the way it seemed ESPN’s cameras captured it and the way an army of online lip readers interpreted it?
