Raiders Countdown to Kickoff: 21: Who wore it best, who's wearing it now

Just three weeks now from the start of the Raiders 2015 regular season opener. The second preseason game is done and the third is up next. With the first roster cutdown immediately following. With exactly three weeks left, we take a look at a guy who won three Super Bowls with the Raiders wearing the number 21.

Who wore it best: WR Cliff Branch (1972-85)

The man who was so good, Al Davis spent 25 years trying to replace him following his retirement. And he never could. Branch was fast. Really fast. He could also catch very well and usually demanded double coverage as a true deep threat. He joined the Raiders as a 4th round pick in the 1972 draft and lined up opposite Fred Biletnikoff. During their time together, Biletnikoff had the most success of his career and the Raiders won their first Super Bowl.

By his third season, Branch was a fulltime starter and was an All Pro. He was named All Pro three straight seasons from 1974-76. The last of which culminating in winning Super Bowl XI. Branch was a fulltime starter for the Raiders for all three of their Super Bowl titles.He finished his career in 1985 as the NFL's all time leader in post season receiving yards. He is also third in franchise history in receiving yards catching 501 passes for 8685 and 67 touchdowns. The two guys ahead of him -- Tim Brown and Fred Biletnikoff -- are both in the Hall of Fame.

Who's wearing it now: CB  Dexter McDonald

Was the team's final pick in the seventh round of the 2015 draft out of Kansas. The 6-1, 200-pound corner is trying to break into a young cornerback group and not get lost in the shuffle. We will find out in about two weeks if he was able to do it.
