Great signing! Rodrigue is tracking just behind Skinner at the same age, he has shown a solid record of improvement every year. He should battle for the backup job next year and could settle in as the Oilers 1B in the near future.
He will be the backup next season, because Oilers can't afford to spend on the position with Campbell's upcoming buyout.
If they put Rodrigue through waivers instead, IMO someone should pick him up: he's 6'1", highly drafted, has good AHL stats and now on acheap contract.
