I don't know of the exact percentages of how much they will be under center. This article (
http://www.omaha.com/huskers/footba...cle_afdba5e3-59a9-5004-a1c8-d02b2615e3dd.html) says, 'He (Riley) knows the Badgers’ scheme well. In a sense, it’s Riley’s own scheme.' So you can expect a similar style to Wisconsin. Chryst was Riley's OC for a few years.
TE use will be up from the last couple years (based on change of QB and spring game), but lack of experience at the position will be an issue this year. TE has been a huge recruiting emphasis since the new staff has arrived. Pelini left the position in poor shape due to lack of underclassmen.
The FB was used extensively when Janovich was on the team. Less so last year. Having Ben Miles come on board as a scholarship player shows they want to utilize the position.
