I say since Super Bowl I because I’m not looking for some receiver from 1920 when the league was 4 teams and all white guys.
I honestly can’t think of a noteworthy whitey WR. Can you?
Steve Largent?
Cris Collinsworth
Wes Welker?
Austin Collie, Kevin Walter, and Wes Welker are tearing it up right now. Dallas Clark and Witten have been tearing it up from the TE position.
Largent is #12 on the all time career yardage list.
Dallas Clark was first on my mind, but he plays TE, and that’s where he belongs; he does very well at that position, but he probably doesn’t have the speed to excel at WR.
Dwight Clark.
Ed McCaffrey.
Don Beebe.
Don Maynard.
Lance Alworth.
Danny Abramowicz.
Fred Biletnikoff.
Dave Logan.
George Sauer
Steve Watson
Ricky Proehl
Raymond Berry (his career ended the season after Super Bowl I 
)
Wayne Chrebet
Ed McCaffrey was the first person to come to mind when I saw the thread title.
The correct answer. His stats are ridiculous:
819 catches, 13089 yards, 100 TDs
Jay Novacek
Fred Biletnikoff
Dallas Clark
Ed McCaffrey
Steve Largent
ETA: I included TEs because of the title. If it’s just WRs then obviously there’ll be a few changes.
One of Elway’s favorite targets. 
I always liked his little neck popping thing after a tough catch. That guy could take a hit.
Slight hijack, but in that same time period, have there been any white starting cornerbacks other than Jason Sehorn?
In the late 80’s Scott Case made the Pro Bowl as a corner for Atlanta. He was eventually moved to safety, but he was a good CB for a number of years.
The white CB is probably the rarest bird of all.
As to the WR question, I agree Largent is the answer.
Before Jerry Rice ran away with the category and hid it, Largent was the best receiver in NFL history, so yeah.
We had a white CB on the Skins once, Pat Fischer. But yeah, that species is now extinct.
I think tight ends don’t count, but we have a good list. Interestingly, there is only one “speed” guy of the names I recognize: Beebe.
St Louis Cardinal Hall of Famer Roger Wehrli played from 1969 to 1982. The saying was that he could run faster backward than he could forward.
Cowboys Cliff Harris and Charlie Waters mostly played strong and free safety, although Waters did a short stint at cornerback as well.
Agreed, that seems to be a particularly rare combo. The only other two I can think of off the top of my head from recent years (and only one was really any good):
- Tim Dwight
- Jeff Query (tremendous speed, dumb as a post, never seemed to be able to learn to run patterns)
I seem to remember that the Cowboys had a fast white guy at one point, a few years ago, but I’m failing to remember his name.
