Ato Agustin has seemingly picked up a lot from Yeng Guiao ..... IIRC, Agustin's last PBA stint was with the old RED BULL team.
I see a lot of Guiao in Agustin's style of coaching ..... preference to tough-minded players, toughening up those who arent, letting the players play through rough spots, equal-opportunity offense (though Cabagnot will drive the plays), etc.
One thing is definite, Ato Agustin hasn't followed the Ron Jacobs-school of slowdown, motion offense which has produced more than a few disciples e.g. Uichico, Tanquincen, Favis, Altamirano, etc.
