Paston is always hesitant in coming off his line so I agree he was at fault. Sigmund, however, was far from blameless either though.
It was Sigmunds fault. When in doubt kick it out.
It was about 8 yards out, Paston should've been out taking control or yelling at Siggy to get rid of it. Sigmund made an utter hash of it too though, I agree.
