I'm totally guessing here, but I wouldn't be surprised if Harris waits until the spring to see if anyone transfers out of Iowa State at semester or following the season. If Iowa State doesn't have enough spots for him even after all of that, I have to imagine another school will get in on him late so he's not just forced to choose between Memphis and Colorado State.
I had the same thought... Tyler is way to talented to not draw interest from major programs if he waits to the late period and major programs miss on other PG targets.
The last two classes that Prohm has put together are very talented and I would expect they will see the floor early. If one of ISU players didn't like their situation it is possible the may try to find a place that they can get more minutes.
To be clear I don't want any of the current Cyclones to leave but, can see a situation were it could happen and be best for the player.
