Horrible examples. You're talking about Hall of Famers who played 18 and 17 years, respectively. Sure they weren't fooled in their prime but early on? I don't remember Ray's early career that well, but...
How many times did you see Peyton Manning fooled by a defense?
As a Pats fan, I saw him fooled for, oh, about the first 4 or 5 years of his career. ****, in the 2003-04 championship game (end of his 6th season) the Pats had him completely confused and picked him off 4 times. Guy had no idea what was going on then.
Look, I understand the frustration but the truth, as usual, is somewhere in the middle between the current rate of improvement and "one game".
