The major difference at this point should be obvious

Wentz has obviously shown them why they can believe in him and have confidence he can handle it.

You, on the other hand, expect the coaching staff to show Goff why they can believe in him and have confidence he can handle it. Goff has nothing to do with it. It's not his job to show them, it's their job to show him.

Maybe the Eagles are misjudging what they've seen, but at least they obviously think he's forced the issue rather than them having to carry him to it.
