Sam Darnold has made a strong impression with the New York Jets and could be the team's starting quarterback if he continues to absorb the playbook at his current pace.

"Are we giving him bits and pieces of the offense or are we throwing everything at him? We're throwing everything at him," coordinator Jeremy Bates said. "If he can handle it, if he can prove that he's the starter, then that will take place when the time comes."

Darnold will compete with Josh McCown and Teddy Bridgewater in training camp.

"If you treat them like a rookie, they'll become a rookie, so we threw the whole book at him to see what he can handle and what he needs to work on -- just like the other two -- and he's done a really good job," Bates said. "Ever since rookie camp, he hasn't flinched."

J.J. Wilcox was on the verge of signing with the San Francisco 49ers when he changed his mind.

Wilcox is now expected to sign with the New York Jets, according to sources.

The reversal stunned the 49ers. He had agreed to terms on a one-year contract and was meeting with the team's defensive backs coach before practice earlier this week.
