This may come as a bit of a surprise to some people, but David Johnson's job is not as secure as you might think.
If you don't already know, the Steelers are planning on keeping nine linebackers and six wide receivers this year. I think Antonio Brown will handle kickoffs and punts, but there's a good chance Tomlin decides to keep Stefan Logan.
If that does happen, cuts have to take place elsewhere. I picked tight end for two reasons.
The first is because since we have so much talent at wide receiver this year, we don't really need three tight ends. The second is because since we have a fullback and two other players capable of playing that position, we don't need an extra tight end to play fullback.
Obviously Heath Miller makes the roster, and Matt Spaeth is the only one truly capable of backing him up. Sean McHugh isn't going to make the roster whether we keep three tight ends or not.
So that leaves David Johnson as the odd man out. If we cut Logan, then Johnson stays on as the third tight end.
