A turnover is far worse than a penalty in any and all situations. I get that Blackmon scored and it was called back and all... but how many TD's have been wiped off the board due to an OL holding or something, and that OL is still playing? If the standard is that if you screw up, you are out... then it should be held to the same standard for the rest of the team as well... not just 1 player.
And Blackmon should be returned punts and kickoffs over Juergen's period. Blackmon is so much more of a threat than Juergens ever will be.
