First of all, consider this is from the rag USA Today.
Second, why trade Collins, and then have Leary play. This makes no sense if from a future salary cap hit. Because of needing to pay all the OL?
Collins has 2 years left on his contract, and Leary will be a FA. So wouldn't you rather give Collins that money. As opposed to possibly not having either next year, plus free will need to be replaced soon also.
As to win now consideration. That don't work either, it hasn't in the past, nor will it now. See what they have in TC first. But who out there could possibly come in that is proven more than a need to protect the franchise...if Romo is not protected, not even the 4 best DL in the league will help this team win.
Now if they would want to trade Leary, another players, or Leary and a little bit of a high draft pick, like a 2nd [as our 2nd rounders don't ever seem to work well anyway], to SD for Bosa, I am in.
