It was a chance to go back up 17 but agree with your assessment
And it was huge passing on that field goal
Detroit was up by 17
49ers drive down kick a field goal cut it to 14
Lions drive right back down and have the opportunity to totally negate the field goal San Francisco just kicked and kick one of their own to put it back up to 17 again
He decides to get greedy and go for it and they fail
Right then and there is when the momentum and the game turned around
Should have kicked the field goal to put the lead right back at 17 again there was just absolutely no reason to go on 4th down
