#5 R-Truth - 47
R-Truth actually debuted for WWE back in 1999 as an ally of The Road Dogg. He stayed until 2002 before departing for TNA. In TNA, Truth was an upper mid-carder and won both the TNA Tag Team titles and the NWA Heavyweight Championship.
In 2008, he returned to WWE and has primarily been a mid-carder regardless of which show he has been a part of. Truth is still in fantastic shape and despite being closer to 50 than 40, he's still athletic enough to put on entertaining matches with practically anyone. The younger generation has also been able to learn how to be professional, and how to take part in serious matches and comedic storylines from the former United States Champion.

The recent addition of the 24/7 Championship has reinvigorated Truth's career. It's showcased his comedic talents once again while also proving why different people are valuable to the roster in different fashions. Truth is still not likely to become a major champ in WWE. Without him in the 24/7 Title chase, however, that belt would lose some of its luster, due primarily to Truth's ability to make it seem important.
