Seriously, a DB can cover a 100/100 sprint/quick WR better than a 65/65 guy - he'll react to the cutbacks quicker, get on the cuts faster, it's insane how the phyisicals level of the WR will actively boost how quickly a defender reacts to them doing anything.
I imagine it's done to prevent large blowouts with passing, but it's annoying. Or it may be related to the 'pursuit fix' that happened a long time ago that made the entire defense react faster to HBs who have high quickness values.
People complained about Rob's AA team and deep passing got nerfed. That seems to be when it all went haywire. The cushion DBs had on WRs was extended based on speed. Footwork was buffed going backwards. Chase Down became Cover Expert and got a boost. Other nerfs came after. The end result is that speed on WRs isn't nearly as impactful. Because like you pointed out....you can simply roll a slow CB and add deflection to his build to counter. They can't get burned like pre season 30 DBs.
Beyond that, Defensives get away with low cov tech way too easily. Right now fast receivers can't burn you deep or shake a 50 sprint, 30 cov tech DB on routes all that much. Compared to elusive RBs who will burn a slow defender fairly easily.
