I agree that it's unfair to ever compare anyone to a Hall of Famer. There just aren't many other guys to compare Hader to, because I have never seen anyone make guys like Bryce Harper and Joey Votto look foolish. So, Hader is 23 and had 12.84 K/9 and 4.15 BB/9 in his first season in the majors as a 23 year old. Johnson made it to the Expos in 1988 (born 9/10/63, so he was around 25 when he was called up), when he threw 26 innings. The Expos traded him to the Mariners during his rookie season, a year in which he struck out 7.26/9, while walking 5.38/9. He didn't get his K/9 above 10 until 1991 when he was 27/28 years old, and that year he walked 6.79/9. It wasn't until 1993 that he finally learned to keep his walks down. Even while walking guys like crazy, he had value as a starter, accumulating 10 WAR in those 4+ seasons, and averaging around 6 innings per start. Once he got some control, he became a dominant force who somehow was able to keep it up for a looong career. I would guess that some here would have been lobbying for the 25 year old who couldn't throw strikes and only had two pitches to be moved to the bullpen, or just kept in the minors until he learned how to throw strikes. Heck, the Expos traded him away. Fortunately, the Mariners saw enough from a guy who had definite control issues and who threw his fastball/slider combo around 95% of the time to keep him in the rotation. Eventually the control came around and his tertiary pitches got good enough for him to throw them around 10-15% of the time and he became the Randy Johnson everyone knows. Comparing anyone to Randy Johnson is unfair, but we have a guy who can do things to hitters that other pitchers just cannot do. We need to try to maximize the value of this guy while we have him because, as others have said, he is the best option we've had for a homegrown #1 starter since Ben Sheets. By the way, even with the walks, Johnson was often able to keep his WHIP in the low 1's because he was so hard to hit, but he never posted a 0.99 WHIP like Hader had in his age 23 season... but Hader will never be a starter because of his control issues. You make many good points. So many of you think "this is what he is" with Hader...that he's a finished product at age 23 and won't improve/adjust. Sale has had years and years at the mlb level to work on and hone his changeup. Hader's has been improving his entire time in the majors. I can again point back at the stat of how many top tier SP started their career relying heavily on the fastball, throwing it 65-70% of the time...which is not far off from how often Hader uses his. And to those saying using Hader 3 times a week is more valuable than every 5 days as a starter clearly have no idea what they are talking about. Good bullpen pitchers generally throw 80 innings in a season...80 is a lot. Starters throw 200. Would you rather have 200 good innings or 80 good innings? In this case, Hader would be limited to 160ish most likely...160 > 80 last I checked.
