Things are going very well on all fronts, Pepperman.
IMO:
1) Punting will boil down to Rastetter vs Coluzzi. I think Rastetter will win the job. When he gets good contact, he can jack the ball; I'm talking 55+ yard punts. The key for him have been his clams; initially, they'd be of the 10 yard (!) variety. Now, I'm hearing they're in the 35 yard range. As you saw in spring game, his directional control is decent. Coluzzi is very consistent, without super highs/super lows. Not sure about his directional punting accuracy.
2) FG will be between Mick and Miguel. I think Miguel will win the job. His comfort range is 48 yd. Hasn't missed a PAT since HS ; ) That is NOT meant as disrespect to MK. The op is going very well. No one knows the future, but I wouldn't be surprised to see 80+% FG conversion rate, after "first game jitters" are over, that is. LS will be Kluver, of course. 3 different holders are in the regular rotation at this point: Rastetter, Coluzzi, McCarron.
3) KO will be between Coluzzi and Miguel. Not sure who will win the job. Both are similar in terms of distance (65 yd, 25% of kicks in the 70 yd range), which will place importance on directional kicking. Miguel is very accurate. Not sure about Coluzzi.
Our new kickers/punters are good. They just need to develop strength, as they're currently experiencing the expected drop in distance kicking the lovely Nike balls, lol.
