How do Players retiring or being traded impact draft?

[*ochocincos*]

What really hurts teams is unplanned retirements, e.g. Boling.
It seemed that they were banking on Boling being the LG for 2019, and then drafted Jordan to groom behind him (or possibly Westerman).
But Boling ended up retiring in July, and it may not have been known prior to the draft.
Then Westerman really didn't step up to take that spot, also ultimately retiring.
It resulted in basically forcing Jordan into a starter role, of which he clearly was not ready for.

With that said, if it was known that Boling was going to retire prior to the draft, they were terrible at coming up with a plan to replace him.
