There is some mixed reviews about Kennedy on this Plymouth Argyle forum. I looked at this forum from time to time last season and, after a strong start where they were much taken by him, then his performances tailed off a bit and posters started to wonder if it was all too good to be true. However, towards the end of the season he seemed to redeem himself somewhat and finished the season in an improved way. Perhaps his up and down performances are reflected in the views expressed.
