He's not the perfect striker by any means, but you're over simplifying to question that all he offers is physicality. It's also unfair on both players to compare him to Godden. Max can play with his back to goal much more effectively than any other member of our squad, draws fouls and consistently gets us up the pitch. His first touch, decision making and finishing are all hit and miss, but that's why he's playing for us and not Norwich or Brentford.
Godden is clearly a better finisher, but playing against the typical Championship centre half, he'll win considerably less than Max when playing direct into him, but will run in behind them more effectively.
Robins clearly trusts him to be doing a job for us right now and looking at the other teams around us at the bottom of the table, I'd not swap him for any of their main strikers. Having watched Kazim-Richards yesterday and Frazier Campbell on Friday night, they're certainly not players I'd take over him.
