I am fan of Blue Bloods and I honestly was wondering when the plug would be pulled.

Not surprised by the timing because in order for Season 14 to happen, the cast had to take a 25% pay cut. On top of that, several support players won't be back. 14 seasons though is an excellent run, in my opinion.

NCIS has already had 2 spin-offs begin and end (New Orleans and Los Angeles). Mark Harmon hasn't been starring in the series for at least a year (I think it might be 2) but I believe he's in an Executive Producer position.

The one that *needs* to end is Law & Order: SVU. That thing has been going for 25 years! The rebooted Law & Order can go away too. The series had a rep for unforeseen twists and I stopped watching with the "twist" could be seen from a mile away.
