Thanks for the hard work.
How many starters do OSU, Iowa and UW return?
For Iowa, guard play was a mess last year with injuries so it's hard to designate the returning starters there. I'll go by # of starts instead:
LT - RSSR Jackson, 36 starts
LG - RSJR Kallenberger (?), 5 starts
C - RSSO Linderbaum, 13 starts
RG - RSJR Schott (?), 6 starts
RT - TRSR Cronk, 40 starts [at Indiana]
Other possibilities at G:
RSSR Banwart - 7 starts in 2018, back-to-back knee injuries in 2019 spring and 2019 season. Hard to say whether he can recover or if he's lost too much time.
RSFR Britt - "The Future", 0 starts, redshirted after 4 games of action in 2019
RSSO Ince - 0 starts, saw action in 11 games in 2019
RSSO Plumb - 0 starts, saw action in 13 games in 2019
