Although I think Cade was a flop for the most part (i.e. lack of charisma, etc.), I actually found him somewhat entertaining in the end (i.e. whenever he would try and save Jericho, he'd get his ass kicked).
At No Mercy for instance when he tried to help Jericho (and got his ass whopped), people in the crowd actually found it funny.
In a strange sort of way, the ass-whippings were actually helping Cade get over. I kind of wished that the WWE made something into that (perhaps similar to Patterson/Brisco from the glory days when they were Vince's stooges).
Aside from that though - I didn't see much in Cade...and don't care too much that he's gone.
One guy who I wouldn't mind seeing be Jericho's *new* lackey, is
D'Lo Brown.
D'Lo needs to get over with the fans again. D'Lo has great charisma and can be an AMAZING heel. D'Lo being Jericho's right hand man would serve him well in my opinion. At a much later date (12-18 months from now?...or later), the WWE can use the awesomeness of D'Lo's heel character to turn him back into a face (or just keep him as heel).
In order to be a tremendous face, you have to be a tremendous heel first (well...for most people).
