To prove I am not biased, I will say that Ian Gold, Travis Henry, Montrae Holland and Dre' Bly are rated too high. In fact Ian Gold has been completely useless all season and Dre' Bly should be an 88-89.
However guys like Brandon Marshall, Chris Myers, Jay Cutler, Marcus Thomas and D.J. Williams are rated a little too low. I think EA ( I'm not bashing them) are a little too strict when it comes to bumping breakout players ratings up.
Read this about Brandon Marshall:
Check NFL Stats if you don't believe me. Someone with those kind of numbers is definitely a top 10 NFL receiver and should therefore have a top 10 rating in Madden.
Also Jay Cutler should be around an 86, he's having a better first 21 games than most Hall of Famers/ Future Hall of Famers could have dreamed of.
