Well, if this is true why are there so many p5 misses in the NFL? Using stars to calculate probability of success is one thing, establishing limits on any player that has been evaluated and targeted by coaches is something altogether different. NFL introductions point out the misses every Sunday. Late bloomers alone make accurately ranking even 90% of players based on their play through their Jr season highly improbable. So if you are signing kids from that 10% pool after seeing them up close and personal, life CAN be good. Better risk reward odds on those who started shaving in the 6th grade and played for strong highly visible programs and got to go to a lot of camps, BUT sometimes schools get to see players after the Jr season highlights are published. Some growth changes, speed work, and better coaching at camps and 7v7 type outings can also be predictors of high end potential. Running behind really bad lines, catching passes from a weak armed QB, being the only real OL on your team can make evaluations impossible. Defensive guys have it a bit easier to excel individually. Sacks and pressures through double teams are what they are, and covering stud outside receivers too. Tackling, making right reads, and making the right drops can be evident regardless of the skill levels of your team and the opposition.
