I actually think the poor bastard is going to go down the Aakash Chopra route rather than Mark Richardson. Renshaw will compile a series of tough unappreciated 30s-40s and they'll forget the fact, like this test, that his stonewalling was a very key reason Australia weren't a house of cards. When the time comes to wield the axe, they'll look straight at his raw numbers and dump him. His mates would have gone smash-em bro on dead tracks get their averages looking solid.
Similar thing happened to the young Khawaja, held his own with some dogged batting in losing circumstances but didn't impress selectors. Khawaja went away, found a middle ground and thankfully made a comeback. Might not happen here, nor should Renshaw have to go and manufacture shots.
