I have some high rated players about to leave, cause I can't sign them. I put them on the trade block. One guy is a 90's WR

Why cant you sign them?

No idea, had this problem last season too

How do you knw you cant sign them? Is it a window that pops up after offering the contract? If so what does it say? Id like to help if i could

I keep offering them extensions, and they reject. I offering more then they want. I'm not sure if its cause my cap is already tight?

yes it is
They wonder if you will have enough to pay them

You have to give them the bonus they want. That’s the first thing you have to check. it doesn’t matter the over $. It’s all in the min bonus they will except.

Just my opinion, and of course we might have different ideas for who to keep but:

3 QBs that are on hefty contracts. Peters is in his finally year. If he isn’t your long term answer trade him or worse case cut him. No bonus money so minimal cap hit if you trade. Figure out what you want to do with London and Tatum. Tatum you can extend to 6yrs and save cap this year and forward.

TE/WR. You can extend Billy TE and save cap this year. Same with WR Wicker and Bowers

DEs Walker and Smith. Same deal. If interested I can continue with more but I don’t want to waste anyone’s time. Good luck.

If you aren't using jsid's spreadsheet, be sure you are. It beats trying to guess at this stuff.
