Agreed, it was a tough decision because they had similar averages but went with Buchanan because the worst he has done is 32 whilst the worst that Loko has done is 28 and Toutai has done 18.
Buchanan's best was week 1 with a 47, he then put in a 44, followed by a 39 and a 32. Playing Melbourne I think he will be in that zone again, so somewhere between 32 and 40.
Loko has put in a 44 week 1, then a 37 followed by a 51 and then a 28 when they were fully outclassed.
Really all Loko needs to do is be involved in one play that he creates a line break, or a try assist and he will beat Buchanan easily. Score a try and he blows Buchanan out of the water. Playing the Sharks who will be Carney less, and with the Parra team pumped to put in a good performance after getting smashed last week, it wouldn't surprise me if Parra win, and Loko is a part of that.
As I said, just too much upside for Loko.
