I don't remember Glock doing anything special, apart from his podium finish in Hungary, and that came about due to Massa's engine blowing up and Hamilton's puncture.
In 2009 it was Trulli who was getting the car up into places, and Trulli had 4 retirements compared to 0 of Glocks.
Yeah he is getting wasted though, and is probably the best short term solution, but even then, it's highly unlikely he will get considered.
