Rhett Ellison did a good job at FB last season. The Vikings also have Zach Line, who was not a FB in college, but he has the tools.
Felton is out for a bit, I think we want to keep Line.
There is one practice squad spot open. I wonder if they will slide Line into that practice squad spot once Felton gets back. I think they want him around when Gerhart leaves.
Ellison got a lot of time in last season as a lead blocker. Asiata and Line both can also provide some blocking for the first three games. No need to sign any short-term fill ins.
