Was he any good? At football, I mean. Other than that, I don’t care about this person. I don’t care what he does with his penis.
He was regarded as a standout college player, but that doesn't always translate into a superior NFL player. He played for Stanford U and won a college ball trophy which made recruiters think that he was going to be big news in the pros.
I remember him as a 49er, less as a Raider because he played five seasons with the Niners and only one season with the Raiders.
When he played for either team, their records weren't very good. Not really his fault, but he was known as an offensive player whose penalties often sent his teams' ball backwards rather than making progress down the field towards the end zone.
He was 'good' as in 'Good enough to play six seasons in the NFL' for a couple of teams that weren't much of a threat on their opponent's schedule.
Ranking him from 1 to 10 as a 'pro football great', he'd be a 2 or 3. Nothing to get excited about.
I'm being kind here.
