Monty is a free agent this year too, so I’d assume they get Saquon instead? Id rather stick with Montgomery if we can sign him to a decent deal, he’s a solid runner and blocker without too many injuries. Really adding a WR and O line should be priority, should be easy to attract since they have a ton of cap space too.
My money is on either bringing Montgomery back on a frontloaded 3-4 year or riding Herbert's rookie contract for another year or two and either bringing in UDFA or practice squad darlings for depth.
You don't see a lot of resources thrown at the rb position the way you used to since A) they get hurt a ton, B) there's a bunch of unemployed or underused talented ones and C) more and more "rushing yards" these days are being racked up by qbs and by wrs catching laterals or passes behind the line. Obviously you don't want to sign the next Leveon Bell deal when you can get the same or better production from a rookie for a tenth the price.
And you could absolutely argue its the right approach. Look at the teams who do go out and invest in superstar backs.. When's the last time one won a ring? The last one I can think of is the steelers with Bettis and he was basically just a figurehead by the time it happened. The Pats won all their rings without a notable running back on the roster.
As someone much smarter than me once pointed out, running backs win fantasy games while Qbs and defenses win real life rings.
