Trask resignation ends an Oakland era

After more than 25 years with the team, a professional sports trailblazer has departed the Oakland Raiders.

Amy Trask had been Raiders CEO since 1997. She was the first woman in a major leadership role in professional sports.

Trask was known for being a staunch supporter and confidante of the late Al Davis -- essentially an extension of Davis in an ownership role until his death in October 2011. Her departure is not surprising; there has been rumbling that Mark Davis, son of Al Davis, has been looking to take the Raiders' business side in a new direction. Davis could make a new hire whose focus would be on securing a new stadium.

Trask was known for being tough and strong-willed. She was well respected in the NFL community. I wouldn’t be surprised if she lands another job soon in professional sports.
