EVERY year we have this same argument and every year we have to read this is these forums that BPA is BPA no matter the position... NO... ITS NOT! thats not how this works...
Teams go into round 1-3 or 4 rounds and they have a set of needs for those rounds then they have values for players at those needs. So lets say for example
CB, WR, LB, DT is a need.. they value their biggest need first... and then they have values at all those positions. So lets say first round the 4th best CB is available but they have a WR that they slightly value higher... They will pick the CB and do a slight reach. BPA is best player at NEED. Given this situation and this scenario if the best player is a TE for example, under this scenario they will not grab the TE... they will get the WR or The CB... BPA AT NEED
