See, that's where 90% of the arguments in MFN come from. Do you have MFN replicate actual football or do you have MFN as a stand-alone simulation? Everyone has their own opinions on this and it's created a division amongst owners in MFN.
I'm NOT for allowing punt blocks, I think it's an awful exploit and a shame when it's the reason teams lose games. I'm simply trying to point out their side of the argument in that yes, in the NFL WR/TE/DB/LB do play on the line during punt blocks.
Those owners are proponents of making MFN a realistic, NFL-like, sim whereas the rest just want MFN, while mimicking NFL qualities, to be it's stand alone thing.
