Incoming freshman KS Reeves Mundshau may determine how the coaches feel about having Siebert carrying all kicking chores. (I prefer Mundshau redshirting with Siebert successfully doing all the kicking).
After Michael Hunnicutt's late season problems a few years ago, it is worth keeping an eye on.
Siebert's kicking against Ohio State early on spawned at least three articles (Oklahoman, Tulsa World, OU Daily) to be written on his kicking woes and Stoops, who believed at the time that Siebert was okay with doing all the kicking chores, still had to reassure him to just "let it go" as far as thinking about his Ohio State problems.
Siebert finished 2016 with an 11 for 16 success rate on FG kicking.
As for his Sugar Bowl field goal that was tipped, that can be the kicker's fault as well as poor blocking if the kick is made with too low a trajectory.
With Perine, Westbrook and Mixon gone, the kicking game in 2017 will have no margin for error, even for one game.
