Sort of...I mean there will always be the starter and a backup.
What it is probably more of is your developmental guys are no longer developing at your place...
Why sit at NU when you can start to Toledo and make some cash and transfer.
I try to look at it if it was me or if it was a family member.
Would I rather sit and maybe get paid "something" or leave, get paid more (hopefully) and play.
It is such an interesting situation because you get 5 years...and then it is gone, forever. It is like a great sci-fi book...and the last chapter is 5 years from the start of the book and it is "your end".
For me, I am a creature of habit and I hate moving/changing, I would 99% stay. But I can see why others leave and you are kind of right, the 2nd stringer is sort of dying out.
