Just get the line up there, make sure they are set and ready to cover the pressure, and let your kicker focus on the uprights.
These portal entries reminds me of basketball last year when several guys who had exhausted their eligibility (DeBruhl, Johnson) put their names in hoping that some waiver might be granted.
