I've seen many posts about O-line that talk about tackles vs guards, D-Line differentiating between tackles and ends, Linebackers between ILB and OLB, and finally Safeties vs CBs. Can anyone give a fairly comprehensive answer to how to differentiate amongst those different positions, and does it matter which division you're in? I cut and pasted this from the "Guide to the Game":
Position Most Important Secondary
DT TKL, STR, TECH ELU, ATH
DE TKL, TECH, SPD, ELU, STR, ATH
ILB TKL, GI, TECH STR, ATH
OLB GI, SPD, TECH, TKL STR, ATH
CB TECH, GI, SPD STR, ELU, HND
S GI, SPD, TKL ATH, STR, TECH
