Seattle Seahawks general manager John Schneider already has said the team won't break up its core players just to pay quarterback Russell Wilson.

On Wednesday, Schneider led journalists to believe that his stance has created tense negotiations with the Seahawks' offensive leader.

Seahawks threaten to let Russell Wilson walk if his salary demands are too high?

"On whether reporters could ask if things have gotten sticky in the negotiations, Schneider smiled and said, 'No, you can't.'"

At issue is the raise due Wilson, who is in the final year of his rookie contract and is scheduled to make $1.5 million this season. ESPN reported that Wilson could be seeking a deal that is worth $20 million annually.

Meanwhile, Wilson upped the stakes in an interview with NFL Total Access, NFL.com reported.

"I'll tell you this, it would be very hard, it would be very hard," Wilson said when asked if he could play both sports. "But I believe if anybody could do it, I could do it. I played two sports my whole life. I think it's funny when people think that the whole baseball thing is kind of a ploy or whatever.

"For me, I've played baseball since I was three years old. I've loved the game since I was a young kid, so for me, I've loved both sports. It was my dad's dream and it was my dream. I don't know if it's going to happen, but I'll tell you this, I won't give up football."

The Texas Rangers own the baseball rights to Wilson, whom they selected in the Rule 5 draft in 2013. Rangers general manager John Daniels said the team would not interfere with Wilson's NFL career.

Wilson said himself that he won't let baseball interfere with his football career, but if negotiations continue at a "sticky" process, Wilson might to start investigation what NFL teams are open to talking about him playing both sports.
