But that does not change the fact that when your team is losing badly in the biggest game of the year, smiling and laughing on the sidelines is a very bad look.Brock Purdy had initially left the field but did return to the game later when backup Josh Johnson left with a concussion, although he clearly wasn't fit enough to play. The Eagles ended up winning the game 31-7, clinching their first Super Bowl berth since 2018.For San Francisco, it was their second straight conference championship loss. They also lost to the Los Angeles Rams 20-17 last season in a game they led 17-7 in the third quarter. This time, the 49ers did not stand a chance whatsoever.Brock Purdy vs. Trey Lance: Who will be the 49ers' quarterback in 2023?Since both Jimmy Garoppolo and Josh Johnson will be free agents, it's going to be a battle between Brock Purdy and Trey Lance.Both have strong arguments. Purdy proved himself in a tough situation as a rookie, and his contract will be cheaper, which is very important in the long term. Lance is the guy the franchise traded a lot of picks to move up in the draft and pick, so he has a very strong argument also.What's going to happen, then? There will probably be a training camp battle between the two guys, and whoever seems more ready will win the job. Trey Lance has a higher ceiling, but Brock Purdy has proved himself in the pros. This is likely going to be one of the very best stories of the offseason.
