ill have to disagree without reading going by title only..the QB is and always has been they hardest to fill and find a gret qb..elite or not..DL DT DE all very important in team building as a CB/DB is i mean we are talking about team here..
sure if you get licky to get an elite defense to cover upa weak offense led by a lessor qb, yes then your debate becomes true but no ones trading an elite NT like umm who are they name them how many are there, for Tom Brady(or others like Montana, big ben, etc etc Pmanning etc etc) in his prime.
you have to have great talent everywhere so if its not NT its DE or 3T its not necessary to have an elite NT i dotn know many true 1T in this era that are considered elite. Not hybrids, true NTs.. name them? them, show me how they won a SB because of just their presence??
how many 1st round and 2nd round picks plus players are given up for a NT? i see this all over the league for QBs..rigfht or wrong QB is always king..
