Yeah, I'm talking career more than year. Although I'll point out that while he does have 45 in 45 this year, Ronaldo has 42 in 40, so even when we talk of them being past their best, Ronaldo still manages to narrowly outperform him on goal to game ratio (and Messi isn't far off). The difference in games is mostly because of Real Madrid getting thrown out of the Copa del Rey for fielding an ineligible player.
I think Suarez is "at their level" this year, but it's arguable whether or not he has actually surpassed them.
Still, all three of them are 29+, so we'll be seeing them decline in the next few years, probably... I wonder who will be the next person to win their first Ballon d'Or?
