Hull boss Mike Phelan questioned the Tigers' "pretty boys'' after they slipped to another damaging defeat at West Brom.
The visitors gifted the Baggies two goals in their 3-1 loss at The Hawthorns, their ninth game without a win in the Premier League.
Chris Brunt, Gareth McAuley and James Morrison capitalised on poor defending to complete a comeback win for Albion.
Robert Snodgrass opened the scoring, but Hull fell apart after allowing Brunt a free header to equalise four minutes after the break.
The second-bottom Tigers are three points from the safety line and Phelan was left frustrated with their fragility.
