He won't move Cirelli for maybe 2 more good years tops of Stamkos. Cirelli is not an average forward anyway, so replacing him isn't some simple thing. If the next two or three years were all that JBB cared about, then Serg remains the correct choice to move for many reasons(worst bloated contract, still best trade value, excess talent at that position).
Just because there hasn't been any news doesn't mean much really. Very little news ever leaks out of Tampa until the signing/trade etc is basically happening. The money for Stamkos and enough other players to reach 22 is still there as long as Jeannot and Sheary are moved, and Stamkos is willing to take maybe 6. Tampa was never likely offering him 8.5 or even 7-7.5, and Stamkos and his camp had to know that, even before they signed McD (as whether it had been Hanifin traded for, McD, or other space needed, Tampa was going to need a decent amount of space for other positions thos offseason).
Maybe JBB is fine letting him walk if Stamkos won't take what his best offer is. Yzerman basically did the same thing 8 years ago with the considerably under market number of 8.5. If Stamkos wants a big aav for 2 or 3 years, more power to him, but it won't be in Tampa. Either way, moving Jeannot and Sheary should still occur, as JBB could then still be able to go out and spend 5.5-6 on a good ufa F to help replace Stamkos should he leave. I think JBB is fine having 2 or 3 800kish contracts this season, and hopefully he will be able to find some value in a couple of ~1 million type ufa's that could be signed(not to mention likely thinking a Syracuse promotion like Goncalves, Groshev, Finley etc contributing).
