When you're an NFL head coach, there are certain things you can't say in a media setting.
New England Patriots coach Jerod Mayo is in a tough spot. While everyone understands the Patriots aren't starting third overall pick Drake Maye because New England's offensive line and receivers aren't good enough to support him, that's not something you say out loud. Maye's development is the key factor. The franchise doesn't want to ruin their talented rookie quarterback.
But Mayo made a bit of a mistake as he dances around that topic. He's a rookie too, after all.
