When Muller shows me he can lose 3 or 4 starters and reload, then I will believe he's not in a rebuilding year next year. Marshall has done that repeatedly and WSU has been told in every one of those years that WSU was headed toward the abyss because of all the player losses.
Muller has replaced A LOT of players during his time at IlSU. He either runs them off or they leave of their own accord. Marshall has had his share of player turnover at WSU. Marshall's player turnover seems to be based on playing time. Muller's appears to be players who don't mesh with Muller.
