As a result of his strong start to the season, Kalman will join up with the rest of Andy Robinson's squad for a training camp in St Andrews next week.
He told the Scotsman: "I have improved but I think the whole squad has benefited from a long pre-season where we all got in pretty good physical condition. Then when the World Cup players were away there was an opportunity to play on a regular basis and build a bit of form.
"It's human nature that sometimes you get a little disillusioned or down-hearted, but that's one of the great things about the period we've just come through where lots of people got an opportunity to play, and that's what we all really want.
"I'm not the only one who has seized that opportunity; you only have to look at the young guys coming through.
He added: "I guess that shows the potential depth in Scottish rugby that people don't quite give us credit for.
"We can excel during World Cup years where maybe other teams don't have the strength in depth to do so."
