I wouldn’t worry about Cornish too much, he looked fine last week. On the missed FG the ball was on the right hash and he’s left footed, the kick had plenty of leg. The blocked FG was just poor blocking up front coupled with the fact that is was about 47 yards out (should have been a chip shot if the offense doesn’t go backward on each play) so he would have had to get it low to get the distance on it. If he misses a few more consecutive attempts then it may be time for a change.
