Clarkson was not overly concerned by the 19-point loss despite his side failing to capitalise on its dominance in the opening term.
The Hawks had 10 more inside 50s and eight more scoring shots than the Dockers but kicked just 4.7 to lead by 13 points at the first change.
Thereafter, the Dockers midfield took over with David Mundy, Michael Barlow and Nat Fyfe seizing control in the centre square.
"Their bigger bodied midfielders really caused us some concerns over the course of the afternoon," Clarkson said.
"They deserved their victory, they played really well. We were a little bit off.
"We're not going to cry too much about this loss.
"We've played some pretty good footy over the course of the year, so we just have to lick our wounds a little bit and get ourselves ready for the Cats next Saturday night."
The Hawks appeared to come away unscathed as far as injuries are concerned. Matt Suckling was subbed out at three-quarter time after rolling his ankle but Clarkson was certain it wasn't serious.
"It was at a time when we were considering who we would sub," Clarkson said.
"So it was an easy call for us. He actually went back on to the ground after he was taped up. We needed to make a call on a player and he obviously had a slight niggle to it."
