my memory isn't great, but didn't we have a similar problem to the Baylor/K-State games during Niang's freshman year, or maybe the Kane year? I seem to remember a Tech game that we completely blew the end of the game, and there was much consternation about getting a quality shot and who should take it, and then they figured it out.
This reminds me of that - learning how to win close games is something you can only do by being in that position.
Yes, ISU had problems with end of half shots for a long time. The offensive game plan was typically Lucious, then Kane, then Monte dribbling around, jacking up a long two. People complained endlessly, but somehow seemed to revise history that ISU was running some of these magical set plays at the end of the games, when in reality it was get Royce the ball and let him make a play vs. KSU, let Scott C. bank in a bomb vs. OSU, let Naz hit some miracle 3s vs. OSU x2, let Kane make a tough shot vs. UNC and let Monte make a tough, tough shot vs. UT in the BTT. And of course Niang and Burton made some huge shots at critical moments too.
It seems like ISU is just missing the guy that has both the mindset and ability to execute consistently, including hitting FTs, right now. I think we will get there, and by the end of the season it could be any number of guys.
