‘Coach Jon Gruden continues to say that Brad Johnson is his starter, but the signing of Rob Johnson and the high praise Gruden continues to give Shaun King are clear examples that Gruden wants a collection of more mobile athletes at this position. One of three players with starting NFL experience at the spot, Rob Johnson figures to make the competition at QB quite fierce. He doesn’t possess a quick release but he has a very strong arm and is usually accurate. He is quick to leave the pocket and make a run for it, but Gruden seems to admire that kind of ability. Though he has been in the league awhile and has had some success, Rob Johnson still lacks confidence at times. A summer working with Gruden could change that. The bottom line with Rob Johnson is this: for around $1 million, the team further improved its depth at the most vital spot on the roster. Like Ryan Leaf a year ago, Rob Johnson was a bargain the team couldn’t pass on. . . .’
