Solid signing. Will provide some depth and he is already familiar with team. Interestingly enough, remember Alonso was traded to the Niners for Kwon Alexander in 2020, now he is back with the Saints.
So they wait until Kwon is signed by the Jets, then go get Alonso, who hasn't played in forever because of injury? I mean I guess they have their reasons and all but from where I sit Kwon would have been the better choice.
