Your post doesn't require refuting b/c it's beyond outlandish. There are plenty of 5'9 players in the NFL - it's something called TALENT. You obviously didn't have it.
The fact that you wanted to play LT at 5'9 175 is laughable. Be realistic. You can "work" and "try" all you want but you don't have what it takes. Fact.
There are PLENTY of CFL players with all the measurable of NFL players. What's the difference then? What's the difference between NFL players and CFL players? It goes beyond size/speed/strength. Ya, that counts too obviously, but you need all of it: football smarts, instincts, speed, strength, agility, work ethic, dedication. You disregard that and say "anyone can simply run with a WR". No, anyone can't.
