I've already given you something Sam Williams definitively does better than Aiden Sezer.. he sets up more tries, and more linebreaks. If you've bought Sezer for his defense prepare to be let down - he's ok at best. That's probably being a little generous.
Pretty much the only thing he brings is his kicking game. But you're losing (the difference in assists) something at the same time - and you've paid a good whack under the cap for what isn't a huge gain (a bigger gain for your club specifically than perhaps some others because of the kicking game, but still not a huge net gain) and also failed to address the areas that needed it more; centre - or fullback if Wighton is considered to move back there but I doubt it - and an extra high quality middle forward.
