re: If BI signs his extension, who is leaving the team?

Smart business if indeed this is the case. You time the extension around Zion’s expiration to avoid losing cost control in BI’s expiring year. You pay Herb and have the upcoming year as a prove it for the team and use as a pivot when it’s time to pay TM3. I’d also sign Hayes to use his or Nance’s salary in a mid year deal.
