I just do not see a trade with the Leafs that involves Parayko or even Pietrangelo. I just don't see how the Blues will end up a better team in any transaction with the Leafs. I say that with all due respect. Along those lines, I would like to thank the many Leaf fans who have maintained discussions with us with knowledgeable and insightful contributions. I think that Leaf fans get judged unfairly, just because they are a large and diverse fanbase.
It's pretty rare that you trade a talented player for mostly futures and you end up being better, at least right away. The idea is more about setting up yourself long-term with picks, prospects and essentially resetting your core, especially when Pietrangelo is set to make a lot of money in less than 2 years time for what is likely his "last" big contract of his career.
I don't see a trade between the Blues and the Leafs either unless the Blues would accept receiving mostly futures for either player. If they would rather make a pure "hockey trade", then we're not going to be good trading partners I don't think.
Armstrong is a damn good GM though so I think he'll make the proper decision with your team. Always seems to make good decisions, outside of being able to find a goaltender.
It's always nice to see thoughtful and insightful discussions that doesn't result in belittling a fanbase. Cheers!
