It's not that Roger would leave if Shaq did, but at least, the team needed a future plan.
Roger was not unwilling to accompany the team through a rebuild, provided it was a team with a plan.
If the Magic were just using him as a box-office guarantee without caring about the results, Roger did not want to waste his prime there.
