I saw earlier they want Abram back on the PS like last year. They called him up 3 times and then signed him for the rest of the year. Plus Howden did start a good portion of last year due to Mayes injury. Harris came from Detroit show he knows the D mostly.
Harris and Howden are more versatile than Abram, and more than likely he will be signing to the PS if he is not claimed similar to how he started last season with us.
