Although, I'm a dirty rotten liar, I have one comment more to make, before I'm responded to and get pissy and such.
Clemens had bad luck. The run support was horrible, but it wasn't just that. FWIW, I lowered Carp's RS to Clemens and in his games (applied evenly), it wasn't a major difference (I could be messing up a bit, I did this a couple months ago). However, consider this situation with the scores (I know, really extreme, but humor me)
Pitcher's Team - Opposing Team (assume he went all 9 IP each team, like he's superman)
0-1
1-2
1-2
2-1
16-4
The pitcher is 2-3 with a 2.00 ERA, a total of 10 ER (say they are all ER) in 45 innings with an average run support of 4 runs per game.
5-1
4-2
4-2
4-1
3-4
2.00 ERA, 4-1 record, a total of 10 ER in 45 innings with an average run support of 4 runs per game.
Really, even though I like the RS stat, there is more that goes into luck than the win to ERA ratio.
That doesn't remove the likelyhood that Clemens was horribly unlucky for what he did in terms of offensive production and support in the pen, but it's a consideration. It also helps that a lot of games that could have been losses for Carp were NDs, while not a whole lot of wins changed hands with luck (which I can only attribute to durability and a strong back of the bullpen), 21-5 looks more impressive than 21-11 after all (making up numbers here).
