It really doesn't but Stafford has always played indoors and would probably prefer that. He doesn't have a no trade clause but if they trade him somewhere he doesn't feel comfortable with, he can still refuse to go and just sit the season out. At that point the Lions get nothing like what Barry Sanders did. Stafford is a millionaire so I am sure he would be ok with not even playing anymore if the Lions wanted to play hardball.
I saw a similar list tonight and I can't remember where but it listed 8-10 teams and San Fran was not on it. I had to keep reviewing it to see if I missed it and they were not on it. Indy and Denver were their top choices. Go figure. I think Garopolo might have a no trade clause and an expensive contract so maybe that's it.
