The 17-32 record as an NFL starter and the threat of being replaced during the offseason first by Deshaun Watson and now possibly by third-round pick Matt Corral hasn't made Sam Darnold any less confident in his abilities.

"As long as I know what we're doing, what the defense is doing, I'm confident I can be one of the best quarterbacks in the league."

Coach Matt Rhule, who hasn't ruled out bringing in a veteran at some point, went so far as to say that he hadn't seen anything like it before.

Rhule said that what Sam has been through has been very hard. Everyone is wondering if you can do this or not. A guy who has shown up has a little more edge to him. He is very focused.

Going from focused to one of the best quarterbacks in the league would be a big leap.

Since the New York Jets selected him with the third pick of the 2018, he has ranked as one of the worst quarterbacks in the league. His first year with Carolina, his total QBR was ranked 29th among qualified quarterbacks.

He was ranked 33rd in 2020 with a 32.9 rating, 25th in 2019: 45.9 and 28th in 2018: 45.9.

In four seasons, he has thrown an equal number of turnovers as touchdown passes. He has a career completion percentage that is the worst in the league.

The Houston Texans were willing to give up three first-round picks and players in order to get the players they wanted for quarterback Deshaun Watson. Carolina is interested in acquiring a veteran quarterback.

A league source says that the Carolinas are keeping an eye on Baker Mayfield if the ClevelandBrowns agree to pay most of his $18.6 million for the next two years or release him.

Everyone, including myself, knows the situation. I have a great attitude about myself.

Since he arrived in the NFL, he has had an issue with his feet.

There were times last year when my feet got very loose.

This is a make-or-break year for him as he enters his fifth and final year of his contract.

I could get caught up in the wash if I were to think about it like that. I focus on executing that play when I am on the practice field.

As a quarterback, you have to be constant, even in the games. You have to be consistent every single day. It is difficult to think about what can happen in the future.

The former USC star has had to learn a new system four times in his young career, and his future is with Ben McAdoo.

Playing quarterback is hard enough, if I start thinking about that other stuff.
