As a distance guy, Sprinters really do make the bigger difference, as a 3k-10k can do one event 100% and then the next day do one at 90-95% which cn translate to 5 place or even more depending on how things shake out. A sprinter can run a 60 and then a 200 and still be fresh. That being said, they cant drastically fill holes in your other events, meaning Iowa is going to need a dream meet to win.
Ohio state always has a good team(2-4) but never great as of late. PSU same boat as Iowa/Ohio state.
It comes down to:
Indiana - Lots of distance, DMR (1st or 2nd), stud high jumper, top sprinter 60/200
Decent(5-9) scores: triple jumper, heptathlete, vault
Huge holes in: mid distance, throwing, 4x400, 60h
Wisconsin - Distance, top2 in DMR possibly 4x400 as well, 2 stud heptathletes (top 3), 400/600/800-good depth and couple studs.
Decent(5-9) scores: PV, Shot put, 60h, Robertson top 5 in 60/200
Huge holes in: weight throw, triple jump/long jump/high Jump
Minnisota - Blankenship, abda in 600, 2stud PV, Stud weight throw, 2 top4 heptathletes
Decent scores: Mead still on mend(and different big ten), hutton in 800, 4x400, DMR, 60h, TJ
Huge holes: Sprints, 400, distance depth, HJ, LJ, shot put
Unless Indiana or Wisconsin have a great day(and the other crash and burn) and can run most of the table in distance, Minnisota will win.
