I used to be one of those, "It wouldnt be ethical to target people based on personality"... but then I realized how effective personality is on NFL quarterbacks! Seriously, every year there is a big debate in the NFL draft and about recently drafted players. They all have physical tools to succeed. Some people blame the situations they are put (bad teams often draft these NFL hopefuls!).
I've noticed that in general:
SJs struggle with being a "gunslinger". They fail to step up to the plate and just "gun it" down the field. The SJ QBs generally either go to their first read, or to their check down reciever (they dont go through the progressions of looking at their different receivers). They can't handle when the play goes differently than planned.
Examples: Ryan Leaf (ESTJ), Jason Campbell (ISFJ), Kerry Collins (ISTJ). These QBs either flop, or have marginal success when allowed to stare all damn day at their first target (and wait for him to get open).
NJs dont seem to have these same "OCD lock onto my first receiver" issues. They often are very vocal leaders of the team, and have a good ability to get on their team mates case. These are the OCD perfectionists that still maintain the ability to see plays through a break down. They know their play books inside and out. They can approach the line with a zillion adjustments at a moments notice. They are perfectionists, but they somehow aren't crippled by it (as the SJ QBs are).
Examples: Peyton Manning (ENFJ), Rich Gannon (ENTJ).
ENXP QBs are the "cool" under pressure QBs. These are the guys who thrive under the tight situations. They literally seem like the luckiest guys in the world sometimes (as these types often seem in real life). They are risk takers, but benefit from exceptional intuition that lets them see things before they unfold. They aren't just risk takers in that "gunslinger sense". They are mental risk takers in their predictions and intuitions.
Examples: Tom Brady (ENFP)
ESXPs QBs are the gunslingers. They have no issues with slinging the ball down the field. They bounce back from mistakes. They energize their team mates. They are competitive, but are not OCD about it. They just "get it done" (when the physical talent is there of course). The ESTPs may benefit from slightly better decision making. The ESFPs may benefit from slightly better "cheerleader" qualities (energizes the team!).
Examples: Brett Favre (ESFP), Philip Rivers (ESTP)
In general, QB drafting/selecting would be a lot better with these "rules":
<> Must be E (possible exceptions ISTP or INTJ)
<> Cannot be SJ
<> Must be compelled to put in lots of study either because they "care" (ENFJ, ENFP, ESFP) or are damn competitive (ESTP, ENTJ). (possible exceptions for ENTP).
I guarantee that no ISFJ will be winning a superbowl any time soon. Go ahead and try this out on any pro QB that you feel you have gotten a good glimpse at personality wise!
If it works for QBs...what else could it work for???
