Spotrac currently projects the 49ers to have $119,909,412 in salary cap space available, assuming a league-wide salary cap of $178 million plus the $59,518,621 in remaining cap the team will roll over from 2017. The Browns project to have just over $112 million.

The next closest team are the Indianapolis Colts at $35.6 million.

The 49ers would like to agree upon a contract extension with Jimmy Garoppolo that could be front-loaded.

"I think we'll always be aggressive," Kyle Shanahan said. "I think we were aggressive last year. I think being aggressive is you've got to look at what your options are and what you believe is the right way to go. Whatever you decide on that, being aggressive is going out and getting those guys. I think that's exactly what we did last year, maybe not a lot of high guys that seemed like it, but we went and got all the guys that we wanted to, that we targeted from the beginning. I didn't feel like we lost on anybody. We'll go into this year the same way."

Six of the top-10 spenders in free agency in 2017 reached the playoffs as it has become one of the NFL's best competitive advantages.
