Could not disagree more with your characterization of Schilling. Won 15+ reg season 8 times, 20+ 3 times, had ~60% win %, 3000+ strikeouts, 4 times in top 4 CY award, top 10 all time in starter WHIP (1920 forward, 130+ wins), spectacular SO/BB ratio of 4.4/1, etc.. Post season: 11-2 record with 2.23 era, 5/1 SO/BB ratio, incredible 0.968 WHIP, Had multiple legendary clutch post-season performances for 3 different teams. Was a Brady-like performer at crunch time on the biggest stage. Took down iconic Yankee teams twice in era defining series.
I did not know Schilling was not in the HoF till I just checked. I guess the sports writers don't like him. Frankly, IMO, it is ridiculous. Had a career reg season WAR of 81, (wins above replacement, i.e., value added to team), greater than Smoltz 66 or Glavine 73, Koufax 53 (shorter career), Whitey Ford 53, Don Drysdale 6, Don Sutton 68, , Early Wynn 52, et al. All are in the HoF. In fact, the only pitchers I checked who were higher was Maddux at 105 and Pedro Martinez 86, there are certainly others. Far beyond a "so-so" reg season player, even most of his detractors would acknowledge that. The media...
Let's take a look at the guys similar to Schilling on the HOF monitor:
1) Zack Greinke and Justin Verlander at both Hall of Famers.
I'll talk about Smoltz in a moment. So 3 out of the 10 guys to whome he's similar are/will be/should be in the Hall. On the other hand, that means SEVEN aren't.
2) Do you think Tim Hudson is a Hall of Famer? Serious question.
Hudson has more wins (222-216), fewer losses (133-146), a similar ERA (3.49 to 3.46), just as many 15-win seasons, three times in the top 4 of the Cy Young Award. No, he doesn't have as many strikeouts, trailing by little over 1,000, and the K/BB isn't in the ballpark, but he's a similar pitcher. And he didn't play for teams with near the talent that Schilling did.
What separates - when you get right down to it - Schilling from Hudson? The post-season (which was my point).
And why is that? Because Hudson didn't play for teams as good as the 2001 D'backs or the 2004 Red Sox.
3) What about Kevin Brown?
Here's another one.
Kevin Brown had five fewer wins and two fewer losses. And his ERA was quite a bit better (3.28 vs 3.46). He got chosen for six All-Star Games JUST LIKE SCHILLING did.
Brown's average season as a big leaguer was 15-10, the exact same record as Schilling and LESS than Hudson's yearly average of 16-9.
Nobody suggests Kevin Brown is a Hall of Famer, but what's the REAL difference between Brown and Schiling? The post-season, which is my point.
4) What about Bob Welch?
Again, another Curt Schilling pitcher career-wise.
Five fewer wins, same number of losses and same ERA. Of course, this is less impressive for Welch because he didn't play during the steroid era and was primarily an NL pitcher. He had six 15-win seasons, including a 27-win season in 1990 when you won what Schilling never did - a Cy Young Award.
This one isn't as close. If Welch had been able to stay away from booze, he's probably a Hall of Famer.
5) Orel Hershiser
Now personally, I'd take 1988 Hershiser over any pitcher I've ever seen, at least during those last two months and the post-season. Fewer wins (by 12), more losses (by 4), and a similar ERA. Four top-four finishes in the CYA voting - and a unanimous win in 1988.
Hershiser misses out because:
a) he actually (as shocking as this seems) PITCHED BETTER in 1989, but lack of offense left him 15-15
b) he missed 1 1/2 seasons due to an arm injury at age 31
So we have two cases where in all honesty the only thing separating them is the post-season and two more with other issues.
6) John Smoltz
Now since you brought up Smoltz, I'll address that. Smoltz cannot REALLY be compared to Schilling straight-up simply because Smoltz (like Eckersley) had two careers, technically three. He started from 1988-99, became a closer for four years and then a starter again. He has 3 fewer wins, 9 more losses, a better ERA, and nearly as many Ks. He has 6 15-win seasons (including a 24-win CYA year in 1996) and four more 14-win seasons (if you lower the threshold from 15 wins to 14, Smoltz beats Schilling, 10-9).
Now let me give one point to you where you are right, and I am wrong - my verbiage on Schilling should not have been "so-so," he was a GOOD pitcher. He was NOT a GREAT pitcher. Not only was the guy never the best pitcher in the league, he was never even on a GOOD TEAM where he was the best pitcher with one exception, the 1993 Phillies. Yes, he had a better year than Pedro in 2004 - because Pedro missed several starts with an elbow injury that signaled the end of his career. But straight up healthy, Boston picks Pedro over Schilling every time.
SHOULD Schilling be in the Hall? Depends.
Is the best player eligible NOT in the Hall? No, because Barry Bonds isn't in the Hall. Roger Clemens, either. But let's set them (and Pete Rose, who is not eligible) aside.
I'm not sure how one would choose Schilling over Tommy John. John hung on too long but to win 288 games MORE THAN HALF OF THOSE after the famous surgery that changed pitcher's arms forever - that sounds like a HOF to me.
Do I think Schilling should be in the Hall based on his on-the-field stuff? Yes.
But it's still the post-season that puts him over - you even appealed to it in your own case. The post-season accomplishments of Schilling DO push him from "borderline case/probable yes" to "yes, he should be." That was the point I was trying to make but failed in verbiage.
Do I think he's cost himself? Unfortunately, yes.
