WR's block like lineman on Heisman difficulty vs User player

I'm down for a challenge with Heisman difficulty but one gripe I have:

WR's block like a 300LB lineman vs the user controlled players on defense.  Unrealistic, needs to be more like Madden. 

In Madden when I am controlling a safety or corner, I can choose a side to run through the WR block, just like in real life.  In real life, the WR can choose to hold me or ride me to the side I choose, it's rare that a WR can block someone like DK Metcalf.
