Analysis - what to expect
Top vs bottom. Best attack vs worst defence. Best defence vs worst attack. If ever a game looked like a foregone conclusion, it's this one. Castleford have been irresistible at times this season and will be licking their lips at the prospect of facing a Widnes side who have only won two league games all season. Castleford's home form is imperious and having averaged 50.2 points per game over their last six Super League home games, the signs don't look good for a porous Widnes defence. Castleford will fancy themselves to post another huge score here and it's difficult to envisage anything else.
