Looking at the depth chart from Wisconsin last year:
OL - Greene and Schlueter are back, expect them to start at tackles, Weyler is back for center, moving Olson to one of guards, and I guess Andries is the other, Oseland and Dovich are backups
QB - as mentioned above, I think they'll only list ZA as the starter and TM as the backup, no 3rd stringer listed (and they probably hope it will go like that the whole year)
RB - as mentioned above, I think they'll have Rod Smith as starter and then true freshman Bryce Williams as backup, but Ibrahim could be there too
TE - Beebe starter, but no idea who the backup is, or if they'll use two TE sets? Ko Kieft? Bryce Witham?
WR - wow, look at that depth chart! Fleck was obviously pissed off at the WR from the NW game ... anyway, I think we're expecting TJ, DD, and CA-B as starters? Or maybe Bateman will start? Phil Howard backup? Seth Green backup?
DE - I think Umlor moved inside, so it's WD and CC as starters, Esezi and Mafe as backups? Devers? Alex Reigelsperger? (only mention him because he enrolled early for spring ball)
DT - Lot of guys who could be here? Gary Moore? Robinson? Royal? OJ Smith? Umlor?
LB - Should be K-Mart, Barber, Cashman, and Huff backup? not sure who the other backups are
CB - I think the guy from Florida is hurt? Terell Smith true freshman starter? Shenault is a senior, backup? Harris, Durr, Estes, Thomas?
S - Winfield and Huff starters? Swenson backup? Not sure
