4th Lines:
1. Bob Gracie vs Martin Gelinas: Each have one major scoring run in the playoffs: Martin Gelinas placing 7th in goals and 8th in points with Calgary in 04, and Gracie placing 4th in goals and 9th in points for Tornto in '32. In addition to this, Gracie placed 4th in asssts in a run with the Maroons where he won a second stanley cup, and has a few other top 20's to go along with those 3 high finishes (although those top 20's aren't that specal, I'll admit) From what I can see, Gelinas's offesive production in the playoffs wasn't as good as Gracie's (and it's not as if Gelinas didn't have god oppurtunities). Gracie also has a reglar season scoring peak that Gelinas can't touch; a 3rd in assists and a 6th in points in 1937. I've only managed to find one top-20 in goal for Gelinas, while Gracie has one more top-20 in assists bsides his big peak season. Overall, I think Gracie is the better offensively of the two.
On the other side of the puck, from what I've seen, Gelinas was a hard-working, physical guy while Gracie was a good defensive, "Pepper" or "aggressive" guy. Nothing that suggests one is necessarrily better than the other in the intangibles department (unless more evidence rises to the surface), although defensive game is not something I have seen noted for Gelinas; but I never saw im play, so perhaps I wrong. For the fairly clear offensive edge however, I think Gracie is the better of the two.
2. Andy Blair vs Ron Sutter- Sutter's only notable offensive finishes in major categories both come in the playoffs: a 20th in points and a 16th in assists is all I can find. Sutter can't dream of Blair's best regular-season offensive peak: a 2nd in assists and a 3rd in points. Blair also has a 1st in playoff goals and points in 1929, in addition to two more top 10's in playoff assists, a top-15 in points, and a top-20 in goals. Blair is easily the better offensively of the two.
Of course, I can not deny Sutter's superiority on the other aspects of the game; Blair brings an aggresive style of game and played on the third-line in Toronto '32 cup win, but Sutter was one of the best defensive forwards around for a time, peaking as a Selke runner-up, and was tough as well. I suppose this depends on what you like more out of your 4th-liners; but at the moment at least, I call Blair's offence and Sutter's defence about equal, making this a wash more-or-less, until I see/find evidence showing otherwise.
3. Bill Fairbairn vs Bill Flett- Interesting match-up; particularly as these two met in the playoffs before, in the 1974 playoff semi-finals to be precise. They also were both in the playoffs the previous year, where Flett was 5th in goals, his only time in the top-20 (unless you count his 8th in the WHA). Fairbairn outproduced Flett in both years, playing less games in both years; let us elaborate, and include top-20 finishes
'73 Playoffs
Fairbairn GP:10 G:1 A:9 P:10- 8th in Playoff Assists
Flett GP:11 G:3 A:4 P:7
'74 Playoffs
Fairbairn GP:13 G:3 A:5 P:8
Flett GP:17 G:0 A:6 P:6 - 17th in Playoff Assists
Very interesting, considering Flett played on better teams in those years.
Flett's other notable finishes in the playoffs would be his 19th in points in the '69 playoffs, and his 10th in goals in WHA '79 playoffs. Fairbairn's other notable playoff finishes are a 12th in goals, 13th in assists, and a 12th in points during the '72 playoffs. Based on these stats, it seems Fairbairn is the better offensive player in the playoffs.
For intangibles, I have seen reference to Flett as a tough as nails player; but that's all. Fairbairn, meanwhile was an "exemplary two-way forward" accoring to LOH, who went on to say he earned his famed nickname of "Bulldog" for his tenacity on the ice. It seems that Fairbairn brought more to the table outside of offence, but even if that's not the case, I haven't seen any evidewnce of Flett being better in intangibles than Fairbairn, which I think he needs to be based on these offensive playoff numbers to be better than Fairbairn. Overall, I'd say edge to Fairbairn.
Fourth-Lines overall: I think my line is the clear better offensively, and gets chemistry points for this quote:
Blair teamed nicely with Bob Gracie and Frank Finnigan on "the Pepper Boys line," a revolutionary third line that was known for its "peppery" or aggressive style of play.
The only clear intangible edge I see here would be Sutter over Blair (unless I see more evidence to the contrary), and I don't think that's nearly enough to make up for the offensive gap here, and would say my 4th-line is the better of the two.
