It really is difficult to predict exactly how next years team will end up. Texas was predicted to finish 3rd in the league by the coaches due to talent and obviously didn't meet those expectations. Meanwhile OSU TCU and TT all hired new coaches integrated a system and were are in or on the bubble most of the year.
I like the fact a number of younger players have been earning more minutes as the season progressed. Jackson, Young, and Weller-Babb have flashed in limited minutes no reason to think they won't improve with a summer and larger roles. As posters have mentioned there will be additions to the roster after the season.
We have been here before specially after the Clyburn and Babb's NCAA Tourney Team. That year Fred had Niang and Naz returning and a lot of unkowns to integrate including talented freshman (Morris, Thomas) late grad transfer (Kane) and JuCo (Hogue). Many predicting no NCAA tourney going into the season that year too.
I am not saying we should expect that type of success as Prohm is a different coach but I don't want to dismiss another tourney team as unlikely either. Next years team will talent.
