The no trade clause just means that Greinke would have to be involved in the trade discussions and/or approve the trade. Until I hear it from Greinke that he would have nixed a trade to the Twins, if there was one offered, I take this as just another writer trying to be somebody on twitter. Didn't Verlander have to approve the trade to Houston? Yes. No trade clauses just give the player final say. It never means that the list, if there is one, or even a full no-trade clause, means a trade can't happen. To say, or infer such, is a bit irresponsible, I think. "Verlander, 34, has a full no-trade clause and had to approve a deal to Houston, which he waited to do as negotiations played out, wanting to make an informed decision based on all options. ............ ........"We thought the deal was dead," Astros owner Jim Crane told MLB.com. "We had tried previously. He's a quality pitcher. I think he's excited to come. He was a little reluctant and eventually made the right decision. We got him for a couple of more years and the team's intact." https://www.mlb.com/news/astros-trade-for-pitcher-justin-verlander-c251757752
