No offence but best thing to do would probably be just to delete and start a new build.
Aside from SP expenditure being all over the place the build itself just doesn't have a long term future (or at least a successful one). Can break it down in further detail but there's a bunch of various stuff: extremely low conditioning cap (especially for a power HB), two of the traits you've chosen aren't that good (specifically slow built + strong base) and the SAs you've chosen aren't particularly useful at lower levels.
Generally it's a good idea to try min/max attributes as much as possible and once you start playing around with builds you begin to notice certain attributes are more important than others - so for example 10 strength is a good idea for a power back, but awareness/confidence not such a big deal since they only affect a handful of skills relevant to the position. Likewise in terms of SP expenditure much better idea just to focus on a few key skills early on so at least he can be effective at something rather than mediocre at everything.
To give you an example here's a pickup HB I was messing around with:
http://glb2.warriorgeneral.com/game/player/239450 - I don't claim to be amazing at building dots or anything but the basic ideas are there: min/maxing attributes to try make the most out of SP cost and focusing SP expenditure on just a few key skills. I'm sure other people could point you to better builds but hopefully that points you in the right direction at least.
