In other words, you need the talent. I guess one could say that the QB, WR, & CB positions are specialty skills where talent trumps everything else as well? A QB has to have the skill set to throw the ball, etc., WR's need speed and solid hand/eye coordination & CB's need a specific degree of athletic talent as well.
There appears to be direct causation between our typical recruiting rankings and where we typically place in the football universe as well as our league. Go figure. However, there are folks here that simply dismiss and or diss those pundits conducting the rankings, etc.
In the end,
"you need the Jimmy's and the Joe's."
