Mahomes first season as a starter was literally one of the top 2 or 3 best QB performances of all time. Brock is doing well, but by the time you stack up his first 17 games vs Mahomes, it will still be Mahomes by a long ways. Brock would have to throw for 3,000 yards and 32 TDs in the next four weeks to be on that level. Sure, Brock will have fewer turnovers, but not enough to really tip the scale.Look, I didn't say Purdy was better than Mahomes, at least not yet. I said it was interesting that Mahomes (who is widely considered the NFL's top QB) has thrown 4 more interceptions than Purdy.
You say Purdy "is not in the same conversation as Mahomes" and it's not fair to compare them given Purdy hasn't quite played a full season. Okay, I guess we could compare their rookie years, but Mahomes only got to play in 1 game his rookie year while Purdy has been setting franchise records.
Time will tell how great of a career Purdy will have. But right now, I can't think of any NFL QB in history (including Patrick Mahomes) who's gotten off to a better start.
The time will come for Purdy when the Niners have to make salary decisions that will affect the quality of the roster around him. Had Mahomes come into the league with the best 2-53, it may have been even crazier season for him. As it was, he had a solid O-line, only 2-3 skill position players worth a damn, and one of the worst defenses in the league.
