One thing I have noticed with Mr Trott is that majority of his scoots from Dummy Half have been utter trash. He tends to run straight into the markers and gets bent backwards a lot.
Along with Dufty, his kick returns have been weak with no intent. I'd assume all of this is down to attitude and mental state and if ya getting flogged and have plodders all around you, you wouldn't be in the best frame of mind.
If he continues like this next year with Reed and Kiks, then there would be cause for concern.
