I share your concern as a Lee owner the past two years.
I think the difference this year is that he is the #4 starter behind CC, Milwood and Westbrook. THis means that he is going up against #4 starters instead of #2's and 3's like last year.
Another point that works in his favor is that the Indians have an improved offense (has not really shown yet but it will) and a vastly improved bullpen. That means he can go 6 or so innings and can get the win.
Seems like he is pitching rather than throwing this year. He is rounding into a very fine pitcher and realizing his potential. Maybe this year he won't be snubbed from the ASG.
