During all this time, Al Davis, who was now past his 80th birthday and in increasingly poor health, refused to hire a general manager or relinquish his absolute control of the team's on-field activities and he continued to make all major decisions regarding draft picks, trades, or signings himself. He came under fire both for this and for strategies that were out-of-step with the contemporary NFL, in particular, his attempt to recreate the vertical game used by Daryl Lamonica and Jim Plunkett. Jamarcus Russell was drafted due to Davis's assumption that he had the proper physical traits needed for this style of play. The signing of Randy Moss in 2005 also proved a costly mistake that consumed large portions of salary cap space.
