Many have said that, but I don't know if that is true. Sure, Mills will need some dynamic players to put up big numbers. But he can be evaluated on field command, accuracy, decision making, poise under pressure, playmaking without Pro Bowl WRs surrounding him. Actually, not having a roster oozing with talent may be a plus for the Texans in terms of evaluation. If Mills moves the team without the best talent it would be a big plus in knowing his ability to handle adversity.
Going back to the thread starter's original question, I'm not concerned about where Mills falls in the QB rankings, or TDs, or passing yards. I'm looking at whether Mills can maximize the potential of the offense. Whether he can lead under adversity. And considering his injury history, if Mills can stay on the field for 17 games.
