I reckon Kyal Horsely will be worth another crack as a low-mid price $280K midfielder to be upgraded. Played 10 games this year and averaged 78. Blease is another around the mark - $290K 13 games averaging 60. Swallow for the Suns is sitting on $274K after 12 games averaging 74 (as long as he stays fit).
It's gonna be a lot harder next year picking rookie upgrades cos GC and GWS have monopolised the trade over the last two years so low to middle priced players will really come into their own.
