That's the thing, us NorthSideBaseball GM's are working with a fraction of the data/knowledge that our front office has. We don't know what next year's potential budget will be, we don't have a temperature on possible off season trade targets, we don't know what their internal projections of this team actually is, and on and on.
It's very easy to say on here "If you trade X player, you need to give a precise plan to justify trading said player". That's just impossible being the NSB GM's we all are.
If the front office has a specific target/plan in mind to improve this team and that includes trading Taillon, then pull the trigger. Last year if that was unloading Taillon and then trading for Glasnow + extending Glasnow we would of all been thrilled (At least those who aren't terrified of his injury history) with that result.
If the plan is to trade Taillon and sign Kyle Gibson for $12m, then don't do it.
mul21 mentions regress to the mean - what is the mean? 82/83 wins? That's the underlying issue most folks have with the current roster construction and why we see so many suggestions on "we need to move x player".
