woverinejay is a member of another forum who brought the ramifications of the 210 point difference between BNC and SQT to light. So rather than acting like this is my discovery, I am giving him credit for his insight.
I do not know. That is an excellent question. Is there some sort of experiment we could do to test for blocking effectiveness? Maybe in practice mode we could hand pick guys and run the same play over and over to see who wins. Or better yet, go into "play now" and use the same lineman. Choose a play, modify the lineman's rating, only for height and weight, run the same play ten times, observe how the lineman behaves. Reset without saving, pick the same play, opponent, and lineman. This time do not modify his height, but his SPD, AGI, & ACC. Repeat & observe.
When you recruit people, keep records. Record their scouting data during recruiting. Then, during position changes, record their actual ratings (before any progression takes place). From your data, you will be able to make your own charts. Or go to many forums on EA's NCAA Football 2007 and do searches and trust the other peoples' work. Or wait until I can access mine, and I will post it later.
