The 49ers converted Joe Staley‘s option bonus to a signing bonus, affecting his cap number for 2015, as CBSSports.com’s Joel Corry (Twitter links) explains. Staley’s cap number has gone from $6.4MM to $7.6MM after his $6MM option bonus was converted. San Francisco, meanwhile, will get a salary cap credit of $1.2MM in 2016. The accounting move won’t result in a salary increase for the offensive tackle. Jason Fitzgerald of Over the Cap explicates the transaction.

Here’s more the NFC…
