Even after four interceptions, even after he admittedly mulled a quarterback switch, the boyish grin returned to Vikings coach Kevin O'Connell's face Monday.
His quarterback, Joshua Dobbs, had just thrown a late touchdown pass to put the Vikings in prime position to steal a game from the Bears. O'Connell had smiled at Dobbs the same way after improbable touchdowns in his three previous games.
It's the type of smile that seems to say, "I'm not sure how we got here, and I thought we were in some real trouble for a bit there, but it sure was fun now that we made it," like a novice skier who didn't realize he was on an advanced hill but somehow survived all the way to the bottom.
Of course, O'Connell and Dobbs have also hit a lot of trees together in four games. Neither one of them seemed comfortable with the other during most of Monday's eventual 12-10 loss, which turned when O'Connell didn't quite trust Dobbs enough to try to get a key first down that could have put the game away — something I talked about on Tuesday's Daily Delivery podcast.
Dobbs looked constrained now that he's more familiar with O'Connell's offense, and O'Connell looked sickened by all of Dobbs' misfires.
Every quarterback can be volatile, but Kirk Cousins represented relative stability: a relatively high floor for his performance, but also a modest ceiling. He was going to stay healthy (until he didn't, for once), run O'Connell's offense and go through his progressions until he found one that was suitably open and safe.
Dobbs' floor is a trap door into a dark dungeon, and his ceiling is the outer space of football. He can make the worst play you've ever seen and the best play you've ever seen in back-to-back plays.
Can O'Connell live with that, at least for five more games? It's a fascinating question that gets to the heart of what coaches want and how much control O'Connell needs.
