I had high hopes for Troy Davis as well. I posted recently on ology that I think he would be worth looking at as a rookie draft prospect if Frawley was to leave. Always seemed to have a bit of mongrel and desire about him, and at 21/22 there is plenty of time to flourish as a KPP. Would likely never be a champ but would be solid backup if required, especially if he was given a limited role or job to do, ala Georgiou.
Some people are very harsh on our young blokes, which is often well founded, but I heard nothing but good things about Troy's attitude and that is one of the most important things you need in your back-up players.
