Neanderthal Quarterback: is an extinct member of the Quarterback genus that is known from NFL specimens found in North America and parts of Canada. Neanderthals QB's are either classified as a subspecies of actually Quarterbacks or as a separate species known as (Benchhisass). Neanderthal Qb's stood about 165-168 cm tall (about 5'5") and were heavily built with robust bone structure. They were much stronger, having particularly strong arms and hands, but dexterity was an issue. Add in slow brain thought process and you can see why they have become extinct in the NFL.
CroMagnum Quarterback: They are thought to have superseded the Neanderthals Quarterbacks is one of the main types of Quarterbacks of the NFL, used for support or back-up. Cro-Magnon Qb's were anatomically modern, only differing from their modern day descendants in the NFL by their more robust Neckbeards and larger alcohol tolerance. Of modern nationalities, back-up Qb's are closest to HomoSapien Quarterbacks in terms of on-field ability. They have the ability to throw like modern man, but their thought process sometimes interfers with reading defenses, therefore not always being able to produce in the NFL.
HomoSapien Quarterback: HomoSapien(Human) Qb's have a highly developed brain, capable of abstract reasoning, language, introspection and problem solving. This mental capability, combined with an erect body carriage that frees the forelimbs
(arms) for manipulating objects, has allowed HomoSapien
Quarterbacks to make far greater use of tools(also known as team) than
any other species. HomoSapien Qb's are particularly adept at utilizing
systems(offenses). HomoSapien Qb's are the only species known to build
franchises as well as utilize teammates to their full capabilities. HomoSapien Qb's have the ability to succed in the NFL and produce for
