His father is former UCLA assistant Ernie Zeigler, who is the current head coach at Central Michigan.
The word we've been hearing is that Trey Zeigler would either go to Central Michigan and play for his father or go to UCLA.
The biggest deciding factor was whether the elder Zeigler would actually sign an extension on his contract at Central Michigan.
It was reported today, in fact, that he did.
While, of course, things can change, most of the sources close to the recruitment believe, now that Ernie Zeigler is firmly entrenched as the head coach at Central Michigan, Trey will choose to play for his father and be a Chippewa.
