The San Francisco 49ers traded a second-round pick Monday night to the New England Patriots for Jimmy Garoppolo, but that doesn't mean they will definitely enter into a long-term partnership with the quarterback, league sources tell ESPN.

With a potential top-two draft pick this spring, and roughly $60 million in salary-cap space this upcoming offseason, the 49ers ultimately could decide to draft their quarterback of the future or use some of their money to sign a free-agent quarterback such as Washington's Kirk Cousins, according to sources.

If the 49ers opted to go another route other than Garoppolo, they always could use a franchise tag on him and then dangle him to the highest bidder in a trade -- and there would be interest, sources said.
