I have a hard time calling Stone a solid 2nd liner. He's only played 23 games...
If there are 90 first line forwards, and 90 second line forwards, than an average second line forward would be around 135th overall, offensively. 90 + (90/2) = 135
The 135th point leader among forwards last year had 39 points. In 2011-2012 #135 had 41 points. In 2010-2011 #135 had 42 points. In 2009-2010 #135 had 41 points. 39-42 points seems average for a 2nd line forward. 33, 34, 32, 32 were the last four full season points for the 180th forward.
Mark Stone had 8 points in 19 games in the NHL last season, prorated to 35 points in 82 games.
Mark Stone had 41 points in 37 games at the AHL level last season, and the rough comparison from
AHL to NHL is 0.44 per point which prorated to 82 NHL games is 40 points.
Mark Stone had 123 points in 66 games in his last year at the WHL level, and the rough comparison from
WHL to NHL is 0.30 per point which prorated to 82 NHL games is 46 points.
This is just speculation, of course.
Here's a comparison as well;
NHL GP G A P +/- PIM PPG SHG GWG TOI S PTSPG
NHL 19 4 4 8 5 4 1 0 0 14:28 36 0.42
NHL 23 5 5 10 -1 6 3 0 0 11:15 37 0.43
The first line is Stone, as a 21 year old rookie. The second line is a 20 year old rookie in '07-'08, Bobby Ryan. Stone isn't the same calibre as Ryan, but he is the same type of player. He has similar strengths and weaknesses. I project Stone to be a 25G, 35A player.
