What "better replacement"s?  All of the previous UH coaches with experience including Naeole have left Rolo & the team. No half decent coach with experience in their right mind would be an assistant coach for Hawaii right now.  The Div1A & NFL coaches are a tight community.  They know what is going on in each school or NFL team in terms of the coaches & team performance.  They all know UH lost to cellar dwellar Nevada & that offensive coach Naeole just quit or was fired.   Unfortunately this has become deja vu chow fun & your suggestion is more like rearranging the deck chairs on the Titanic.  Ain't going to make a difference.  
PS:  Not you but don't want to hear the excuses that Hawaii does not have access to the best blue chip players to play at Div 1A.  After Teo, Marriota, and Tagovailoa at Alabama backing up #1 quarterback Jalen Hurts, others including McKenzie Milton at #25 UCF, the entire NCAA & NFL community knows about all of the top blue chip prospects coming out of Hawaii
