Coach yeng might be thinking that now is the right time for them to be in bigger stage as they are complete now, Ravena is back and Fonacier is fully healthy again. if you see them, they are now very confident with their outside shooting, thanks to the coaching style of coach yeng because it change this team to a more offensive one.
Harris has been on the radar of NLEX and just recently he became available so they gamble and took the risk. Coach Yeng would like to match the import of SMB, TNT and Ginebra which all are more of an outside threat. IMO, they are doing the right move, he showed what he is made against Columbian Dyip and expect him to improve his game.
IMO, Columbian Dyip may not be on the level of SMB or TNT but they have greatly improve now with Perez on board, they no longer are push over.
We saw how both the imports of Gins and SMB really played well against each other, that's a real definition of a good import.
That would be the real test if he faces the TNT and still drop that huge numbers on the stats which i think he will since the guy is a high percentage perimeter shooter.
