First, I felt it was a challenge because I hadto learn many new things. For example, because I'm on offense, I had to learn about 20 different plays as compared to when I played flag football, where most of the time you just run a route and the quarterback throws you the ball. Tackle football has multiple formations and from those formations there are multiple plays. It can get difficult because your responsibilities are different with each play.
Another thing I have to learn is when on defense, I have to know how to tackle the player with the ball. When I played flag football, you just need to worry on pulling a flag on the player with the ball. In tackle football, its more difficult because you need actually need to hit and tackle the player.
Also, football is difficult because while I am running and tackling, I have to wear these very heavy equipment which are shoulder pads, knee pads, and a big helmet for my safety. This makes things difficult because then the equipment slows me down a lot and makes me tired faster.
In conclusion here are three reasons why I think that football was a new challenge for me.
