It blows my mind how many people are just so easily dismissive of Loomis and how easily they jump to "Oh, just get another GM". Look, I'm not aggressively defending Loomis -- maybe his time has come. But what I do feel fully confident about is that, post-XLIV, Loomis was doing what Payton wanted in the draft and in free agency. And his decision to ride on with DA, while obviously wrong in hindsight, wasn't unreasonable based on what was known at the time, and what this franchise's m.o. is.
If it was easy to get a Howie Roseman off the street, everyone would do it. Watch what you wish for, one day you might get it.
