League-wide, kickers are about 60-70%
from 48 yards. Hauschka's accuracy on medium-range FGs seems about average or maybe slightly better to me, so of the poll options I'd say 75%.
This year, Hauschka is 3-3 from 40-49 yards with makes of 47, 44, and 40 yards. He's 1-3 from 50+ with a made 52 yarder, a missed 51 yarder, a blocked 50 yarder, and a missed 61 yard attempt at the end of a half.
Last year, he was 7-8 from 40-49 yards with makes of 43, 47, 45, 49, 42, 48, and 43, and the miss was a blocked 41 yard attempt. He was 2-4 from 50+ last year with makes of 52 and 51, a miss from 51, and a miss from 61 at the end of a game.
On a related note, something coaches always seem to do that really bugs me is settling for a medium-long FG attempt at the end of a game. If we have the ball at the 30 with 30 seconds left, I would hope Pete continues attacking to try and set up an easier attempt. So many coaches run a play to the center of the field, let the clock tick down to :03, call a time out, and send out the kicker hoping for the best. Moving up from the 30 to the 20 would increase the likelihood of a successful FG by about 15%.
