With the 4-3 and 3-4 being the most prevalent base schemes, and with all defenses running a multitude of schemes with defensive players playing multiple positions, IDP needs to be rethought. While yes, we have flex options, we do not have either enough options to make proper flexes, or the proper defensive labels.

PFF and the AP have moved on from the traditional labels on defense after Khalil Mack got 1st team All-Pro for both OLB and DE. We all know that was silly, because he never truly played a 4-3 LB. He's an edge defender. So the AP recreated their defensive all-pro team to account for "edge defender." In conjunction with that, 3-4 DEs got acknowledgement as interior defenders, with Cameron Heyward making the first team last year. The disparate roles overlap. 3-4 OLBs and 4-3 DEs share the same base responsibilities. Defend the edge and rush the passer from the edge. 3-4 DEs and 4-3 DTs also do the same. Plug the B gap and maybe an A gap to draw a double team. Same as a 4-3 DT.

Because of the mischaracterization of 3-4 OLBs as "simply LBs," IDP in general has an overabundance of LB, a lack of DE, and a glut of defensive interior DE who would serve well as a DT (in leagues that require DT), being essentially worthless when compared to someone like Calais Campbell.

My suggestions are to either:

Add two IDP positions. "Defensive interior" and "edge defender."

Allow commissioners to create custom positions and add players to the custom position whenever they'd like.

Or, allow commissioners to put any position in any roster spot.

Greater league and commissioner autonomy could go a long way, but at the very least fantasy IDP needs to catch up with the realities of football. It would go a long way to creating a more enjoyable experience for those of us who appreciate line play.
