Don't think today's move affects Stamkos. We have $5M in cap left. That isn't enough to A) re-sign Stamkos and fill other holes, or B) replace Stamkos and fill other holes if he walks.
So someone else is definitely moving. This fantasy of Stamkos taking a $2-3M long term deal is silly. They need more cap space regardless of if they plan on re-signing Stamkos or backfilling his position.
Adding 6m+ in cap space definitely does effect our ability to re-sign Stamkos, it changes everything
