I think they could find a much younger, cheaper option who could more legitimately be viewed as a center.
Perhaps, but a backup that could cover 3-4 positions, which Taylor could, would be more valuable vs. a dedicated center.
With 7 being active on game day, you realistically need your backups to either be Left/Right or Interior/Tackle.
Right now, we don't have a RT under contract for 2020. Bulaga and Veldheer are both free agents. Assuming we could sign one of them, Taylor could be the 6th man and backup all 5 positions.
If we re-sign both Bulaga and Veldheer (that seems like a pipe dream to me, but I'm hopeful) Veldheer is either the swing tackle and Taylor the interior guy. In a desperate situation where we lose Bhak and Bulaga in the same game, we could survive with Taylor and Veldheer at both tackles.
Again, they could still draft a center of the future, but maybe he's the 8th or 9th best lineman and he's the center of the future. I wouldn't want to waste a game day active on such a guy.
