I like your premise, but I don't agree with all of the moves you mentioned. Malik Turner has played pretty good in training camp and preseason, but he doesn't have the potential that Simi Fehoko has. Yes he has more experience in the league and he also does good things on special teams, but he's never gonna see game day with the Cowboys. I think they keep Simi based on his contract, potential, and the fact that Gallup, Cedric Wilson, and Noah Brown are all free agents next year. All things equal or close to it, the team will keep the draft pick in Fehoko. I'm not saying I disagree with your thinking, but they will give the rookie the roster spot if they keep 6 WR's.

Goodwin may not offer much on defense, but he makes his mark on special teams, and really we don't have many, (or any) other players on the roster that brings it on special teams the way he does. He is the leader in that area and it's not even close competition with the next guys up. You're absolutely correct that it would be nice to have a player that can give more value to the team other than special teams, but the league now is designed for specialist role players and he fits that to a T with his special teams work. John Fassel, and previous ST coordinators we have had recently have all vouched for Goodwin as a leader on ST. And frankly, I don't see Thompson as equivalent on ST, or defense. He got beat time after time last year on defense. I don't think any of us wanna see that again this year.

I'm not sure we see Trysten Hill be sent packing anytime soon. He still is rehabbing and if he stays on the PUP he doesn't affect our roster spots...(53) man roster cutdown. So that keeps him on the team at least until he has recovered and returned from injury. Sadly, also, Jayson Smith isn't going anywhere either. Not with his contract and the affinity that the Jones' have for him.
Is he overpaid? Probably at this juncture, but he has been available to suit up, and the last 2 years...he has led the team in tackles. I know that isn't a ringing endorsement, but he has played decent at times. I also think they will use him in certain packages, maybe with Parsons as the only other linebacker in those situational rushing plays when they attack the edges with LB blitzes. His problem has been the injury he sustained in the bowl game against Ohio State. It's a minor miracle he is still able to play with the nerve damage he has dealt with since. He's a gamer though and you need good team first guys on the team. Plus he is a leader in that LB room.

I wouldn't trade Gallup, unless it's for a top notch CB or Off. Tackle. And I don't think any team is gonna trade their CB1 for a good, but not great #2 WR.

If it were me I'd be looking for a young up and coming DT that can rush the passer and hold his own against the run. Maybe a Kevin Martin type player that Detroit might be looking to deal for WR or LB help.

Hopefully, we both are wrong and the players the team chooses to keep will get us ring #6 this season.

Stay Blessed bro!!!
