But they have, not only in this thread, but across the forum as a whole. The next tier down isn't as exciting as the top tier free agents so those threads get less traffic and exposure. But to say that nobody has offered other solutions is flat out inaccurate.
But this is also missing the point. If they're not going to be serious about going after the top tier free agents, then they need to be realistic and go after the next tier down and sign multiples of those types of players. Ultimately, that's what's going to make this team better because they aren't just a top tier free agent away from winning. They had one last season and how'd that go?
