Pedigree-wise, I do not see anything impressive at all. But pedigree doesn't mean everything.
Overall, he looks put together nice (despite not having good conformation photos to look at). There is something that seems "off" about his hind lower legs, but I'm not sure what it is. He's a little cow-hocked, yes, but maybe he has slightly long pasterns??
Never know unless you try. Just realize this horse is already 5 and has never been ridden. Be willing to invest 1 to 2 years of general riding to get him 100% broke, before you even attempt to pattern him on barrels or games. As long as you are fine with the time committment.

It is not enough to know how to ride; one must know how to fall.
