Wow, this was a tough one. It's numbers like 72 that make me wish I didn't have to separate these guys by their number. There are at least three very deserving players in Raider franchise history one could make an argument deserves to be named as the best to wear it. But unfortunately I must choose just one.
Who wore it best: C Don Mosebar (1983-94)
Mosebar was drafted in the first round by the Raiders in 1983 and unfortunately carried the distinction of being the player chosen just before Dan Marino. It also means he got his Super Bowl ring as a rookie. That year he watched his predecessor, Dave Dalby, as the starting center get his third ring in a Raiders uniform. Two years later, Mosebar would take over as the fulltime starting center for the team, just the third starting center in franchise history.
Aside from the 1988 season in which Mosebar was the team's starting left tackle, he was their starting center for a full decade. In that time, he was named to the Pro Bowl three times. He played 12 NFL seasons, all with the Raiders. All 12 of those seasons were in Los Angeles. His career ended when during training camp in 1995, he suffered a serious eye injury that would ultimately require his left eye be removed.
Interesting fact about Mosebar is he was born on September 11, 1961 which means the incidents of 9/11 occurred on his 40th birthday.
Who's wearing it now: OT Donald Penn
The Dons have it. Penn came to the Raiders last offseason after spending the first seven years of his career in Tampa. He was a Pro Bowler in 2010 and signed a new contract with the team after that season. Then in 2013, he was charged with 12 sacks given up and the team decided to part ways with him, replacing him with free agent Anthony Collins.
After last season, Penn had a resurgent season joining the team he grew up a fan while Collins had the same struggles Penn had in that offense the previous season. Collins has since been cut and the 32-year-old Penn is playing some of his best football in Oakland. His being made available late in free agency was a huge find for the Raiders who had lost Jared Veldheer early in free agency.
Penn heads into his second season in Oakland part of a very good looking left side of the offensive line along with left guard Gabe Jackson and center Rodney Hudson.
