it was mentioned that Tracey was a big part of his progress. Fitz mentioned that the results from the pressure from Tracey flicked a switch for him and made him realise the importance of hard work and how it pays off. I think his motivation would be internal at this stage (with how much recognition he got from last season) and like you said, would be wanting to get his name closer to those elites.
Doubt he flips straight from making a big jump largely due to pressure to not getting anything at all from being pushed though.
And while I am fingers crossed and knock on wood he plays out the season we can't have nobody else training at fullback.
I'd be running Metcalf, Miller and Dykes there too at times. Need to know what plan B just in case and I don't really want starting players being shifted there (Tracey if centre, Hynes and Moylan*).
*even if Moylan misses out to Trindall I still don't want him playing FB
