I'm totally fine with singing no free agents. It's been more or less the plan for the last couple years other than a bad decision to sign Carr. We need to build this team through the draft to build a young core. Then, once we have that we can start adding some mid-level free agents and the very occasional impact free agent.
And it's not a tank. The only player really being cut is Carr and it's not like he's some guarantee of a winning season or the playoffs.
