Well, I'll go with the position everyone's forgotten.

RB. Today RB's are a dime a dozen - and I don't mean there aren't great ones that stand out, there certainly are. But there are many very good RB's, so I don't think they're considered as 2nd most important position because they are relatively easy to replace today... but that overlooks the 'position' itself regardless of the name on the jersey.

The 'position' I think only second "key" to QB... I can easily see a great DL'man, LB'r, CB being considered but the game today is scoring. - JamesJM
