The NFL free agency is not only a means for players to test their value on the open market but also for teams to improve their rosters. With just a limited number of quality players, teams will have to dig deep down in their pockets to snag key additions to their rosters.

According to CBS Sports, the Cleveland Browns and the San Francisco 49ers are said to be the two teams who are expected to spend big in the 2017 NFL free agency market. Armed with a deep salary cap space, these two NFL teams will battle it out to get the best talents available in the open market.

The Cleveland Browns has the most cap space to spare in this year's NFL free agent market. The Browns have over $100 million in free cap space to splurge on players the team wishes to acquire. The Cleveland NFL team is said to be on the hunt for a new quarterback and is said to be targeting Tyrod Taylor.

Last year's NFL season is the worst that the Cleveland Browns ever had. It will not be a surprise if the Browns end up spending more than other teams are willing to spend on certain players.

Another NFL team projected by NFL.com that will probably spend big this NFL free agent market is the San Francisco 49ers. The 49ers is among a number of NFL teams that are known to be less active in NFL free agency. Such may not be the case as the 49ers is in need to fill up its roster in almost every spot there is.

The San Francisco 49ers first priority is to fill up the quarterback position. With the very limited quarterbacks available in the 2017 NFL free agency market, teams will have to compete with each other to sign the best quarterbacks available. Expect teams to offer huge contracts just to get the players they need.
