My concern with Risto is still his skating, agility, quickness and defensive awareness specifically when pucks are in tight around the net.
I liked the progression he showed last season, although his production tailed off mid-season, he improved from a -32, to a -21, to a -9 last season... that's a positive trend.
As he matures, his lack of elite quickness and agility can be masked by positioning such that he doesn't put himself into unrecoverable situations.
One thing lost in the GMTM discussion is the deal he gave Risto. I thought it was extremely fair and didn't overpay or underpay, either on term or dollars. A +1 for GMTM.
