Wouldn't the kicker also attempt some kicks with realistic game trajectory to get their target / stretch distances? I assume that's how the team makes their decisions, and not by looking at unrealistic warmup kicks.Folk isn't the longest kicker, so to reach the uprights he had to kick the ball on a lower trajectory.
That's what a lot of the "hitting it from X in warmups" discussion misses. In warmups, there's no offensive or defensive line to kick over, so the kicker can make a kick that starts on a lower trajectory than he'll take in the game. In game, Folk has to make sure his ball doesn't get batted down at the line, so he has to take a higher trajectory. It's a tougher kick to make than in warmups.
