Tolman isn't the most logical but it's the easiest and softest call to make, at best he's a safe stop gap solution. But for me, Tolman's current skillset doesn't justify a starting position and big minutes with the players currently in the squad, he's just too 1 dimensional and doesn't compliment our Australian frontrow. He doesn't bring an offload, he's slow, no real footwork, no real ball playing ability, barnstorming runs, etc. He needs to bring more than below average runs and good defensive reads.
You just have to look at other teams and see what their locks bring to the table, the majority of them have that extra dimension. Mannering is probably the closest comparison of Tolman at lock, however Mannering brings an offload,some ball playing ability and even tries, Tolman doesn't.
Tolman is a bench player for me next season. We have 2 props that are better than him and i don't want him at lock for reasons i explained earlier, so he's a bench player. He also needs to sacrifice his engine for some size and power. He also needs to lift his intensity instead of trying to pace himself for a marathon all game. I also don't buy the whole "not an impact player" rubbish. If Tolman truly can't add any value off the bench then that's just another reason why he well and truly shouldn't be a starter for us.
