I think at this point we're counting on having Gregory back more than we're counting on Taco. I don't think we have any plans to re-sign Quinn.
Now, there are several moving parts here. If Taco comes on, then we let Quinn go in the offseason because we've got Charlton on the cheap for a couple more years. If Taco fails but the rules change concerning marijuana (notice that I'm not considering Gregory stopping using it), then we've still got a young starter on the cheap through 2020. If Gregory smokes his way out of league and Taco doesn't develop, then either we pay Quinn if he plays great or we're back in the search for a right end.
