Sterling was a better wr, hands down & would've broken a lot of Packers' records. If his career wouldn't have been shortened due to injury, he had an excellent chance of being mentioned among the all-time greats & would've been a sure-fire HOFer. He averages 1.3 more catches per game, 18 more yds. per game & has 12 more TD's than Donald in 64 less games played. Sterling was almost always double teamed (sometimes triple teamed) on teams that were bad to solid while Driver has played on really good offenses w/a great qb's that have had many more weapons on it to take the pressure off of him. Meanwhile, Sharpe never had a good #2 wr on the other side, except maybe in his last year. But, he still put up amazing numbers that year.
Sterling was a man among boys & he also played big in big games too, he should be considered to be in the HOF. In his 7 years, he was a 5x Pro Bowler (when it meant a lot more) & was a 3x All Pro. Compare his numbers to Terrell Davis' & Gale Sayers', 2 other players who had their careers cut short. Don't forget too that Denver had an O-line that could make ANY rb look very good (i.e. Mike Anderson, Olandis Gary).
Donald's been a very good wr & is a great person but he was never a Blue Chipper like Sterling was, never.
