Bringing in a FA WR like Marvin Jones would be a good thing, it seems - but why destroy our WR depth. Next year it will be one of our more thin position groups. After Kupp and Woods there is no proven NFL starter talent. Jefferson may become that, but have we seen enough of him in limited snaps to be sure? Someone like Jones would just add to the weapons.
For whatever reason - Higbee's 2020 was pretty sub-par. Not sure if it was injury, or gameplan but he seemed to be less involved and I'm not sure how good of a blocker he is at this point. It's not that we have great depth at the position - but maybe it's easier to find vet blocking TE's or H-Backs on the cheap. Maybe we could get Everett cheaper than Higbee. They kind of have the same skillset.
Higbee has been really good at times, but when it comes to a pure numbers game - his contract, plus others like Brockers and Havenstein might be too much for the amount of production they bring.
