Suited connectors vs offsuit broadways

[twang]

I ran some sims in Pokerstove and was a bit surprised by the results. Basically I put a suited connector hand of any size against a range of offsuit broadways, Ax and Kx (in other words, hands that people love to play in small stakes games).

The simulations showed that suited connectors has a significant equity edge over the other hands. Could someone explain to me why?
