Heatley/Gaborik/Spezza/Nash/Stall/Perry and that was just taking a quick look of quality players who's games feel off around 30 and that was my point and not some crap about having to have a tight set of conditions to meet like your trying to do since you know your wrong .
Lol,
Comparing like to like is a pretty big part of doing analysis. A muchbigger part than ad hominem attacks actually. How good a player is in their peak and late 20's, if they've already started to see a decline, all indicators of their expected fall off.
Kudos for at least trying, but you're flailing in the wind.
Heatley- fell off a cliff at 29 and was essentially done by 31. Barely qualifies at 20th in scoring, .89 ppg
Gaborik- couldn't stay healthy his entire career, relied on his speed. From 30-34 averaged 50 games per season. Again barely qualifies at 20th, .95
Spezza-good comparison as a cerebral centre. No where near top 20 due to injury, .99. Remained a 60-70 point C until 33, fell off at 34
Nash- a mediocre winger overrated because of tools and international play. 60th in scoring, .73 (no where near qualifying
Staal- another good comparison. 13th, .88. Had down seasons from 29-31, then had 65 and 76 point seasons at 32 and 33
Perry- again barely qualifies at 18th and .88. Decline happened suddenly at 29, held 50+ point level from 29-32
So a scattering of wingers that either flamed out early/ due to injury/ or just weren't as good, a couple of centres that actually support the idea that there's a decent chance he'll remain productive. You missed Lecavalier as probably your best support. But even he was productive, just ground down by injuries.
Against all of the the stars that were consistent to 29 then continued into their early-mid 30's.
