Johnathan Abram appears to be a liability

He's not as much a liability as a necessity as Howden seems to be a disappointment. I guess too much stock was put into Howden winning the SS role. When that didn't happen the team had sign vets Harris and Abram to be able to field a secondary. Looks like Safety will be a huge position of need this off-season.
This is my take as well. Howden isn't the answer and I have not been impressed with his play.
