Blind defense stats

[sl4v3]

After reading the other thread where there was a discussion about defending with K2 in the BB, I decided to look at my BB defense stats and they're pretty depressing. The following hands are my only winners:

suited:
A2s+ (except A8s)
K4s+ (except K7s)
QJs,QTs,Q8s,Q7s,Q3s
JTs
T9s,T8s
98s,97s

offsuited:
ATo+
KJo+
QTo+
T9o

pairs:
88+

I'm thinking I must really play a lot of the other hands poorly (surely I should at least be winning with a few more pairs and a few more offsuit hands, no?). I'm guessing I'm not going to showdown enough with some of my lower pairs as well as A high hands. Anyone have any other ideas about how I might be misplaying these hands (ya, I know without seeing any actual hands, this is nearly impossible, but random thoughts may still be beneficial)? Should I tighten up my BB defense and only defend with my winners?

I'd be interested in seeing other peoples' range of winners when defending with the BB.
