That's true that you don't know how fast I am because I never tell here - nor do I give my real name.
We do though know who Sharif Karie is and we do know his times and his history with running. Almost 100% of what is posted on this message board is opinion, and without it there would be no message board.
Again, I'm not saying he sucks or that he's a bad person, but not every runner with physical talent gets to the upper eschelon of running - that is where, in my opinion the mind has to play a large part. Call it guts or determination or killer instinct, whatever you want. It is my opinion after witnessing his career that he doesn't have those things. I'm just a guy with an opinion, so why the hell do you care? What difference does my opinion make?
Fine for you to disagree with me - that is what a forum is all about, but just because I take some facts and infer something from those facts doesn't make it the wrong thing to do.
