Free-Agent Setup: San Francisco 49ers can retain stars

The San Francisco 49ers have more than enough available money to re-sign all six of their key unrestricted free agents -- running back Carlos Hyde, guard Brandon Fusco, linebackers Brock Coyle and Aaron Lynch, cornerback Dontae Johnson and strong safety Eric Reid.

But can they do better?

This much is certain: None of the players stand out enough to warrant tagging. The best of the bunch -- Reid -- plays a position at which the 49ers have surprisingly good depth, so it's possible he will be allowed to leave.

Coyle's stock got an unexpected bump recently with the arrest of star linebacker Reuben Foster. Lynch almost certainly will be allowed to walk, while the club believes it can upgrade from Fusco and Johnson, so the door is open for them as well. Hyde likely will be back, unless Saquon Barkley slips to the 49ers in the draft.
