Actually he's stronger, looks it and plays like it.
I'll withhold judgement whether "he's ready" until we see him in extended action.
I think one reason Zamula is struggling is the league watched film, noticed he's a little indecisive and teams now try to press him into mistakes. They adjust, you have to adjust.
If I were coaching against Andrae, I'd tell my forwards to bounce him around and see if he starts panicking in the D-zone. He's undersized, make him show he's got sufficient strength, knows how to use leverage, and is agile enough to evade contact and make the forward pay for being overly aggressive.
