Yes, you are, I think. Playmakers last longer. When Messi loses his explosiveness and fails to get behind defenders as easily as now to score goals you can still put him behind a striker and even at 35 he will be able to ping passes around and create chances. His excellent first touch and game intelligence will also remain. Watch Maradona in 1994 when he was 34, fat and full of drugs and what happened to Argentina after he got suspended.
I see Messi without goals, acceleration, and dribbling as a Riquelme. When Ronaldo loses his explosiveness and pace I don't know what he'll do. His game revolves around movement and pace to run into space to get at the end of passes. If he can't lose his marker as easily as now that'll be it for him. He's very similar to Torres and Kaka in that respect who also relied on their explosiveness and once that was lost they struggled mightily.
In theory I agree with you, yes Messi has the skills, vision etc. to be a great playmaker (he wears that hat for us already sometimes). However, that's based on the assumption that physically Messi will still be able to handle it. The playmaker role needs very high work rate, running all over the place. Will Messi be able to handle that kind of work rate? He is used to walking and running for only about 7 km a game.
I just have this feeling that Messi's body is not going to sustain that many more years of wear and tear compared to CR7's and he doesn't take care of it as much as CR7 does, maybe it is the lack of interest or discipline. That red meat at the post-Clasico BBQ we saw?
