I know it is pointless to answer and you will now start the same story of why he stayed at Citroen and he retired when VW came in WRC and blah blah blah... but lets see the number again:
Didn't Hirvonen take it to last rally to decide the title two times (2009 and 2011)? This to me seems there was some competition. Look again to the championship standings from 2004-2007, the differences are greater than you think, except 2007. Remember 2006 he was away for 4 rallies. Here are the average points differences from champion (adjusted to 25 points for win before 2010):
2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2 0.18 5.63 8.75 0.16 0.63 3.17 0.21 8.08 0.62 4.38 8.77 3.77 3 1.61 6.09 8.75 7.34 2.66 9.50 6.04 8.23 2.00 8.92 9.85 9.00 4 2.50 7.03 10.78 9.06 7.97 10.67 10.83 8.38 3.85 9.31 12.62 10.85 5 4.11 8.75 11.56 9.84 10.78 12.00 12.08 9.69 8.62 11.23 12.85 12.23
To me it seems that 2004-2005 and 2010 were the years with the least competition but still you (and some others) only talk about after Marcus retired...
Also have in mind that in 2013 Ogier was way more dominant than Loeb ever was. Does this mean he didn't deserve the championship?
