As it stands we have about $40 mil to play with with before any signings. Tru will probably take a cap hit similar to this years franchise tag numbers (No that won't be the average but Demoff front loads contracts) if we keep him. So that would bring us to $26 mil.
Britt and Quick really depend on their performance but Britt in particular could start costing lower tier #1 receiver money if he eclipses 1,000 yards this year. He's at 492 so we shall see. Quick shouldn't be too much unless he starts to really turn it on. Both are tough to guess costs right now, particularly because we may do some unexpected cap magic. All told it may be hard to justify paying both of these guys because I think Britt takes $7mil a year and Quick will look at the $4-5 range.
So that would take us to $14 mil. I'd subtract $2-3 mil for draft signings. With that we still would want to keep Zuerlein, Benny, and TJ. I don't think we keep Case on this team next year.
The rest of that needs to be used for Donald and Tree's extensions. Donald is becoming the highest paid linemen no doubt. That will probably average to $20 mil a year or even more. It could structure in a way to make the first year hit at $12 mil (just my guess). And Ogletree will probably want $8mil a year.
I know the numbers don't seem to add up, but there are other details that can make all that fit (cuts, restructures, and the structures of all these deals.) Though it will be hard to keep TJ, Britt, and Quick. I'm willing to bet someone get offered more money like Jenkins did.
Long story short, we are pretty tight if free agents are what you are after. And thats if Fisher is still around. If Fisher is canned, Britt probably walks, Quick and TJ are probably not pursued at all and some random guys get cut. If we fire Fisher we may see some splashes in FA. But status quo staying the way it is we are looking at a FA just like this last offseason.
