rugby is a mans sport nfl players wear padding bloody bunch of gays
How much ignorance at the beginning of this thread?
The game isn't rugby with pads. The ball is passed forward which increases the running speed which leads to bigger hits, plus anyone get's hit not just the ball carrier. Along with significantly less safety rules than in rugby the pads are needed.
Even with the pads and helmet the average career in the NFL is just 3 years due to injuries.
Oh and as for 'why do they celebrate after making a tackle?' questions, if you bothered to learn the rules you'd know that the defense stopped the offense from gaining another set of 4 downs (attempts to take the ball a minimum of 10 yards).
