Positive thinking:
Huddersfield beat Birmingham - they both stay below Argyle as a result and as Huddersfield will then lose to Ipswich they are then relegated.
Norwich should have enough to get at least a point v Brum, thereby relegating Brum too.
Sheff Wed I expect to lose or draw v West Brom and then I can see them winning at Sunderland, so we can't rely on Sheff Wed to help us out.
I struggle to see Argyle getting another point except perhaps one at home to Hull, but still unlikely.
So even if Blackburn lose both their remaining games, unlikely they will finish below Argyle. Therefore, Come On Huddersfield!!!
