"On SmackDown!, the heat among Los Guerreros will come to a boil when both Chavo Guerrero, Sr. and his namesake son will form a father/son tag team to face Eddie Guerrero & Kurt Angle. This foursome has been at the center of some of the most intense moments in SmackDown! history during the last several weeks, and on SmackDown! they finally tange in the ring. Don't miss this tag team match where the winner of the battle is not nearly as important as the winner of this inter-family war!"
Out of curiousity, how long has Chavo Sr. been retired? (Not to complain, I'm sure he's still in good enough shape to be carried to a great match by the other three guys involved. Then again, Stephanie McMahon could be carried to a great match by Chavo, Eddie & Kurt combined.)
Steiner has looked better mostly because he doesn't ever wrestle for more than 5 minutes anymore. Thus, he doens't blow up or exhaust his moveset anymore. I wouldn't call that working on his flaws as much as not being allowed to expose them.
