I feel confident saying that those who think Tarmogoyf hasn't turned red Thresh into a distinctly bad matchup for Goblins simply haven't tested the matchup enough. It's really not good. Your main paths to victory in this matchup are getting lucky with land disruption or resolving a first turn Chalice and racing.
It's important to recognize that Tarmogoyf is a very significant problem for you, but I'm not convinced that running Goyfs of your own is the correct plan.
