Unless this article and Google search have mislead me, these are the 2022 franchise tag salaries. There are tender offers also indicated that might be the best way to go for some of our players.
Since Charles Harris was a first round pick, they could offer him the original draft value tender.
I'd want to offer Tracy Walker probably the 1st round tender offer personally.
I don't know if you can have multiple tender offers on free agents but this seems like a good way to go.
Ideally you hope that a player and management strike a deal that both are happy with for more than one year so you can build your team and keep morale high.
