Sorry Draftniks...The Draft is Not Science, Its a Crapshoot

This article represents what I have been saying about the drafting process for years. I know many of you love the draft and that's cool. Me, I just don't care other than who the Steelers draft and if my WVU guys get drafted at all.

I particalary enjoy the part about the '73, and '75 Steelers drafst that bookend the famous 1974 draft. Two pretty awful classes around the greatest class ever.
Take Pittsburgh's famous 1974 draft, one that produced four Hall of Famers with its first five picks. That's a truly amazing performance by the Pittsburgh front office, but its 1973 draft was middling and its 1975 performance was downright poor, as its 21 picks didn't produce even a single start in a Steelers uniform. If Pittsburgh was so great at scouting in 1974, why was it awful in 1975?
