I agree with this and it might be that Nelsen starts based on a potential sale (or just potential). For all we know though Nelsen is one of those guys who has it all locked down in training when there's zero pressure but in a real match he goes full on deer in the headlights.
During our recent skid of creating next to no chances Schaff could definitely have been useful but in the bigger, wider picture he is basically an Oduro type player. Lots of pace and directness but not a lot of anything else.
