I appreciate u for using the song and expanding the reach."Kevin Byard opens up about Shedeur SandersShedeur Sanders' relationship with Kevin Stefanski has been a hot topic ever since he assumed the starting role for Cleveland. Even the little things have taken the spotlight, like when Stefanski didn't give Sanders the game ball after the Browns defeated the Las Vegas Raiders in Week 12.During a press conference on Monday, the coach expounded on why he was taking things week-to-week with his player:“He wants to continue to get better and better, and that’s the right attitude to have, and that’s why we’ll continue to work.”On Monday, Chicago Bears safety Kevin Byard shared his thoughts on the matter on Josina Anderson's "The Exhibit Show":"Everybody knows, everybody sees this guy is talented; and for him to go out there and get a win, especially with the season that they’ve had, I think that would’ve been huge. You see the locker room of the teams that are winning, you see the teams that really care about each other."Until you can develop that type of trust with a player and coach, and a player knows that coach actually cares about them on a human level, it’s hard to connect—to try to encourage this guy. Because if a guy don’t feel like you really care about him, it’s like, I don’t care about you."The Browns' next game is against the Tennessee Titans on Sunday. Kickoff is at 1 pm ET on Fox.
