Or just hire an actual GM. Remember, Jerry is owner, President, and GM. His son may have one of those titles, but it's Jerry. He's in charge of almost everything. Depending on what he lets his coaches do. As he sees it, he built those teams that won the SB all those years ago, so he knows what's best (ignoring that Jimmy Johnson maybe had something to do with it.).
Can't remember the #, but if you don't spend within $30m (??) of the cap the league dings you, just as the do if you're over.
Stafford? They went after Sam too. Didn't do as well.
Some teams have spent big money on free agents and had it blow up in their faces. Remember the Eagles and their "dream team"? How about the money Washington threw at Albert Haynesworth? I'd say the Rams spent a heap of money, but were still fairly smart with it. They partly mortgaged the future, but got a SB win out of it, which matters far more considering how hard it is to win in this league.
Here's one site to view Cap info:
Over the Cap.
Having Whitlock retire, and losing Miller has moved the Rams into a decent spot. They were I think second from the bottom after the SB win. Though 2024 doesn't look good for them. When I looked last they had more dead money, so I'm not sure what happened there.
Sportac is another site that has cap info. So does PFF, but you need a membership to access it.
