Just a guess on my part based on nothing but observing how teams handle these things.
Bradford will be extended to a Alex Smith like contract with a little less guaranteed money. 5 years total length-ish. The team had budgeted him in to the cap already for next year. So if they are happy with his meds. they extend him put most of the guaranteed cash in his first year as a bonus pay him less salary and spread the remainder out over the length just in case it doesn't work out. Risk reward.
If he stays healthy the Rams get a bargain compared to extending him after a great year, if it doesn't oh well.
His agent won't want to take a pay cut in the last year he would rather shop him for the guaranteed money he would get. All the matters is the guaranteed amount, and he has none next year.
The Rams to use that cap money efficiently from not bringing Bradford back need to cut him before free agency and the draft. So that's a crapshoot on drafting who they want for sure. Bring Davis and Hill back draft, a guy to develop if Davis isn't long term.
Bradford's leverage is like Alex Smith's, he already been paid a massive contract. He can pick and chose who and where he plays. Unlike Dalton, Kapperdick etc. he's already been paid and set for life. As long as he can pass a physical he will get looks.
Bradford's agent already knows what he can get for him and where the offers would come from, he also knows what the Rams will do.
I'm not a Bradford Mom, he can be improved on. I might rather draft MM, fire Shotty and move on.
But putting it at 90/10 Rams go all in on Bradford and his new contract by February, draft a OT or WR unless there's a regime change. If somehow they cash out Fisher Bradford will be gone.
