Thing is so many people can win Roubaix, Cav, Greipel, Kwaitkowski and Wiggins so many different sort of riders, yet Cancellara could not win the TDF or Cav, Greipel and Degenkolb. I agree an onform Cancellara would be almost impossible to beat but this year was like a train it was very easy. Cav could have contended this years Roubaix.
Cavendish and Greipel will never contend Paris-Roubaix. Paris-Roubaix
never ends in a bunch sprint. Just because there are sprinters in he end of the race like Degenkolb, Kristoff and Boonen doesn't mean any sprinter can contend for the win. Most sprinters struggle to compete in 250km and most of them struggle to do anything except sit in the bunch and sprint at the end. Degenkolb, Kristoff and Boonen are all exceptionally tough sprinters with a decent engine; so they can participate in 250km races and they can race a bit if they have to. That's why you see them in the end of all tough flat races; MSR, RVV, PR but also at tough flat GT stages.
To compete in PR you need at least the following capabilities;
1) endurance be competitive ater 250km
2) good bike handling skills for the cobbles
3) a big engine; to be able to keep a high pace for a long time without rest because the finale starts with 60km out and there are no descents
4) you can't be too lightweight
5) you need good tactical wit; the race is much less controlled so you have to know which moves to cover
Cavendish is severely lacking in 3) and hasn't shown anything in 2) an 5). Greipel is severely lacking in everything except 4). Tony Martin whom you also mentioned is severely lacking in 1), 2) and 5).
Boonen and Cancellara on the other excel in all of these and have therefore dominated Paris-Roubaix in recent years. They both become better with the kilometers. They both have excellent skills on the cobbles. Cancellara is one of the best TTists in the world. Boonen hasn't focused on TTing, but if we'd have 100km TT's on roadbikes; I would put my money on Boonen. Both of them are >80kg. Both of them have displayed the capability to read a race.
I think that more or less every cyclist who has these talents has Paris-Roubaix as the main goal for their season, or at least one of their main goals.
