All this Lackey criticism is overblown.
1) After taking a few months to adjust to this new environment in 2010, he pitched to career averages after the All-Star Break. And despite some popular opinion, he didn't face pushover teams, he pitched against NYY, Tampa, Texas and LA during that stretch.
2) He has a 5.00+ career ERA in April. Yeah, Lester isn't the only one who struggles early. If you've seen him pitch in 2011, you can tell he put a lot of work in this offseason to get into good shape.
3) He's a good pitcher. He's had two bad starts. Get over it.
