Norm, I'll answer your question this way in order explain my optimism.
The first game of the season we were horrible. My wife thought I would be depressed. I wasn't. This is the year we have to 'take a small step backwards in order to leap forward.' I told my wife that I'm on a '3-year plan.' I expected this team to be horrible but I wanted to see if the freshmen and sophomore would eventually be BIG caliber. I am very pleased with Mack (I think he could be ALL-CONFERENCE by his senior year) and I think Yvan Ouedraogo and Kevin Cross will be solid depth by the time they are juniors and seniors.
I expect Mack to be our starting point guard for the next three years. I do not expect Ouedraogo or Cross to ever be starters for us in future years -- but I see them as excellent depth off the bench (something we have been lacking). Next year, I expect Lat Mayen will start at the stretch 4 position and Derrick Walker will play the 5 position. I hope Lat Mayen can garner ALL-CONFERENCE recognition. I also expect that we will over-recruit some of these players in year three.
For perimeter players, we have seen Dachon Durke, Jervay Green, and Thor. Again, I see them as depth. With Teddy Allen, Shamiel Stevenson, and Delano Banton joining the fray (and Mack), I see a lot of depth and an improved perimeter shooting team. And again, I expect that Hoiberg will over-recruit these guys in time (Juco Japanese shooting guard for 2021).
As you can tell, I see things through red glasses. For me, this is the most hopeful new basketball era we have ever had with a new coach. I expect that he will go through a lot of players before he finds the 9 or 10 that he wants. I believe that it will be sooner rather than later.
