After this weekend I'd put Pendlebury over Ablett.
Pendlebury's composure and ability to move effortlessly in congestion are magnificent, whereas Ablett often bites off more than he can handle and sometimes games the system for free kicks.
Ablett also needs to start trusting the players around him more. He burned Matera this weekend looking for his own slice of glory and it didn't pay off.
Also the Collingwood/West Coast game comes to mind, Pies on the ropes and Pendlebury lifted when the game was there to be won, put the team on his back and carried them over the line.
