While I'm all for SPFL signings and I won't pretend to have watched all his games this season, Theo Bair has real buyer beware potential given how horrendous he was for St Johnstone last year and how Van Veen has looked this season after Kettlewell got a tune out of him last year as well.
On a slight tangent but similar note, Jamie Langfield is goalie coach at St Mirren and has had a real run of turning water into wine with Alnwick, Hladky, Carson and now Hemming taking big leaps forward under his coaching. As much as he was a bomb scare as a player, he's clearly got incredible luck or something going for him as a coach given how many SPFL goalies tend to be muck. Someone we should maybe be keeping tabs on his career.
