Um, not relly - Helton was pretty average from 31-39, he hit 7 home runs in 2008 and 2012 and 8 home runs in 2010. He only hit 20+ home runs once in those years (2005 - 20 HR). He also played in Colorado, which is taken into account by writers. Helton also never won an MVP. Votto won an MVP. Helton was only a 5 time all star. Votto has been an all star 4 times, and I would be shocked if he doesn't at least double that with all of Canada voting for him. If Votto were to repeat 2013 for the next 6 years his career numbers would blow Helton's out of the water.
As of today Joey Votto has the 17th best OPS in the history of baseball.
He has the best 20th OBP in the history of baseball. This ranking will go up if he duplicates 2013's OBP.
If he were to simply duplicate 2013 for rest of his career he would finish among the leaders in the most important offensive category in baseball (OBP) of all time.
