He was under 620k for a total of 3 weeks last season.
Round 3, 4 & 5.
After that he never dropped under 650k for the remainder of the year.
He could have a stinker and tank his price, but people taking the generic straight bat response to a journo in preseason as justification is wild.
It's also a matter of timing. Just because he drops 620k doesn't mean you will be in a position to get him. Tough to upgrade to 600k plus players early in the season without trading another premo.
