Most people seem to be in agreeance that 2nd row bench coverage is a problem. As much as I love Kobe, I feel like he may have to be the sacrificial lamb.
You need 2 middles on the bench, preferably big and/or explosive ones. Then you need someone who can genuinely cover 2nd row but also spend time at lock/prop when required.
From our current squad it would look something like 2 of Taupau/Baker/Willison alongside Hunt (who seems to be our only backrow option unless they sign Patston).
In certain games you could play Kobe as a more mobile middle at the expense of Taupau/Baker, but against most teams I think you need 2 genuine props.
