Let’s say we sign one of Burnes, Fried, Snell, Eovaldi, Buehler. Seems pretty likely. They slot in ahead of Houck, Bello, Crawford, Giolito with Criswell, Fitts, Priester and others as depth.
So if they make that signing and then also trade for Crochet, without including one of the starting five listed above, you have to either move one of those five, likely Crawford, to the pen or trade one.
moving a viable big league starter to the pen seems suboptimal and risky, the risk being jerking him around hurts his value and/or leads to injury from being jerked around
so you’re left trading one for who knows what? Seems understanding that piece is critical to assessing a potential or actual Crochet trade
of course, if you spend big on Soto and it results in not going after one of those FA SP, then trading for Crochet makes tons of sense
