If Lovie fails next year and is fired, what makes you think this roster will stick around with the era of "Free Agency"/transfer portal we've entered into?? I could see many players seeing this as a "get out of jail free" card and bouncing.
To your previous post- Whitman not veto-ing the hire but having the concern to supposedly send multiple resources to Lovie about the backlash and why this may not be a good idea is a sign of JW's management abilities (or lack thereof). He's done well in other areas where an AD needs to do so, therefore I will not pull the "fire JW" card yet.
Also, to the point another poster made about leaving for "promotions" an ASSISTANT to the OL coach in the NFL is not really a promotion from a Power 5 OL coach in college. And with Butkus having left an ASST to the OL coach at the NFL level twice to come back to his alma mater makes me believe he wants this program to do well and he wants to be a part of that staff. But he sees the dumpster fire Lovie has started (and Beckman in Luke's first round as an Illini coach) and he leaves out of frustration from lack of direction.
