The tired argument is a no go. Shoon is out at the 4 minute mark or before every game whether is he doing well or not. Watson and Ward since Kunc became healthy don't even play. They played minutes when ISU was flirting top 10 and up at the top of the conference so it isn't that they don't know how.
A coaching issue........only with sub patterns that I can see. There is zero reason to give a player like Jones those type of minutes against this type of competition unless Shoon needs a blow or is in foul trouble. And rarely is any of that happening at the 17.00 minute mark in the first half. But every game.............there it is. And again.........Watson and Ward. They were good enough to help ISU early be the talk of the country. So what gives.........I have no clue.
Other than that my thinking is they have hit a wall of some sort. It happens to pretty much every team during the year at some point. Bad thing for ISU is it's almost March and they only have a handful of games to figure things out before hey..........wait till next year.
And Shoon still gets tired and has bad fouls even with limited minutes.
Even if they make a run in the tourney they'll get beat at some point like every ISU team has and it will be 'wait until next year' anyway.
