Which top guys are as injury-prone as Kennedy? Rey is the only one I can think of.
Edge would be the best example. Batista also has a poor record with injuries. Shawn and 'Taker are quite often so banged up, they have to write them out almost on an annual basis.
I don't think any of them are as injury prone as Kennedy. Edge would be the closest. When you look at Taker and Shawn, they have taken off maybe 5 months total apiece in the past 3 years.
