The other side of the argument here is if Hammel doesn't have a sub 3 ERA in the first half the cubs probably aren't in the #2 WC spot. Either way, his first half justifies the money they spent on him. Your issue isn't necessarily with him it's with the fact they didn't really sign a more solid #3. Remember they did try to sign Shields. If you consider him the #3 they tried to get with Hammel as a #4/5 starter he's fine. Most #4/5 starters are frankly pretty horrible.
No, my issue is with him..
I dont look at major league pitchers as numbers, i look at them as starting pitchers in the major league that despite what their paid are being paid to get hitters out and keep their team in games for a chance to win..
I dont expect pitchers to be right all 30+ starts, csuse yes there going to be a couple bumps... i just expect consistency throughout the season, not a great first half and horrible second. .
if the cubs are to be yearly playoff contenders now, they need to find starters who wont kill the bullpen in 2nd half and not put all the pressure on other starters to win..
