You are looking at it a little different that what coaches would look at this. Prohm is looking at having Lard, Solo, Haliburton, Horton-Tucker, and Jacobson in the starting lineup. Nixon can come off the bench and add some defensive minutes and fill a few rolls. However, that did not happen. Lard, THT,and Haliburton are all gone. So Nixon has to try and be the man like he had to try and be at CSU. It has not worked with him in that roll.
You don’t take a 2 for one guy unless you believe he is going to provide starter minutes. It made zero sense at the time and it’s played out horribly.
