I think the comparisons are justified

This offense is so great to watch.

It has the great space management. McVay spreads out a defense just like Martz does.

It has a QB that makes quick great decisions. Goff does look a lot like Warner, Bulger, Green.

It has a crew of great WRs that run great routes.

It has the best all purpose RB in the game.

It has a good offensive line.

All of that sums up to the the best comparison of all

The offense puts up a bunch of 30 point games because all of the above.
