ALAMEDA, Calif. -- There is no doubt Derrick Johnson has much to prove in what will be his 14th NFL season this fall, his first with the Oakland Raiders.
After all, the Kansas City Chiefs essentially told the longtime fan favorite his services were no longer needed when they exercised the option to void the final year of his contract this spring.
The question, though, is this: How much does Johnson, who turns 36 in November and has torn both Achilles tendons since 2014, have left in the tank?
“The main reason I’m still playing ball and chasing a championship ring [is] just because I believe I have a lot left in the tank; I have a lot left in the tank,” Johnson, who signed with Oakland on May 7, emphasized on a recent conference call with Bay Area reporters.
