It's possible.
hard to know what move would be best for the Birds. This season certainly doesn't give one a lot of confidence moving forward. The first two seasons under him were very encouraging.
Generally, you can point to things to look forward to in the coming year. For the Birds, I'm not sure what there is to look forward to. The Defense was a problem most of the year. They finally got the safety problems resolved, but the CBs have not been stellar (though Rowe looked good after Carroll's injury), and the CBs haven't been helped by the lack of a consistent pass rush from the 3-4. The LBers were a mess, then Hicks filled in due to an injury and looked good, then he got injured. Not a unit that you expect to be a really good next season.
On offense, where to start. Bradford has been good, and when he was out you really noticed his absence, as Sanchez stunk. The OL is a disaster. Peters is starting to show his age. Kelce was good when called to move but never overpowered on run plays. The guards have been a problem all year. Johnson, the RT, is mediocre. Ertz seems like a decent TE for the future. The WRs have been a disappointment all year. The best of them has been Jordan Matthews. The RBs are a mess, between Murray not being suitable for the offense, and the OL rarely creating holes for them. Sproles is a nice change of pace back, but doesn't seem like a workhorse. Matthews was pretty good, though inconsistent.
It's not as though the addition of a few players will make a big difference. This team needs a major overhaul. In that vein, it might be best to do that with a new coach.
