The only thing “clownish” is not recognizing or acknowledging how different Purdy looked and how limited he was when Trent Williams, CMC, and Deebo were out. It sure wasn’t good.
Purdy, like many NFL QB’s, is only as good as his surrounding talent (and time in the pocket) allows him to be. He’s nowhere near talented or good enough to overcome key injuries or a dearth of surrounding talent as truly elite QB’s such as Patrick Mahomes, John Elway, or Dan Marino can and could.
Further, you guys have short memories, as Jimmy Garappolo played really well and won a lot of games with essentially the same cast minus CMC. That should be your first clue that Shanahan’s “system” and more importantly the surrounding talent is setup and in place for any decent-to-good QB to succeed in. Your second clue should be Matt Ryan’s career before Shanahan then after.
If you can’t recognize that a majority of QB’s starting in the NFL today could perform as well (or better) in that offense, it seriously impugns your knowledge of the game and/or showcases an impressive level of naivete and bias.
Forget Mahomes, Allen, Herbert, Burrow, Rodgers, Lawrence, Jackson, and Hurts — the likes of Stroud, Goff, Prescott, Watson, Love, Cousins, Tua, Stafford, Wilson, and Murray could ALL lead that Niners offense equally as well (and several of them would do so more impressively).
But by all means continue believing that the blind clown isn’t you.
