Wouldn't that have been easier to put in your first post?
No offense, but I assumed someone at your club would have said this by now. What club are you playing in which no one has told you what position to focus on, and basic rules about cleats, and equipment?
I know that comes off as a bit smug, and I appologize for the overall tone of this comment, but I had hoped that the reason you were considering soccer/rugby styled cleats was because someone had mentioned to you that you couldn't continue playing with american football cleats.
Regardless, now you know. Hopefully you've returned the ones you purchased, even though we suggested several ways to get soccer/rugby style cleats, and are going with a better option.
If we can help you out with any information regarding position play, training, rules/laws, etc... please feel free to post it here or shoot a PM. I, personally, will be more than glad to help you out and answer any questions you have.
