He had a decent year last year yes but he's given up 16 earned runs in 5 starts this year. Both him and Lester as well as the bullpen have been hugely disappointing this year although Lester seems to be looking somewhat better. Regardless it's only April but I still think next year or the year after are more likely years for the Cubs to make a serious run. The hitting potential is there and it's young. Rizzo, Kris Bryant, Jorge Soler and Addison Russell who currently has a 9 game hitting streak. The pitching needs to be there too however which is pretty obvious. Without question it needs to improve. The Cubs aren't done putting this staff together though and thankfully so.
I'll admit I'm a little biased with Hendricks because my wife and I actually have met him and spent some time with him when we were on a Cubs destination weekend last year in Chicago. He is really a nice guy (at least seemed that way) and after last year, I am hoping he really catches on and has a good career with the Cubs.
I haven't been this optimistic with the Cubs since I lived in Des Moines and watched players like Kerry Wood, Mark Prior and Cory Patterson come up through and almost get us to the WS. The young bats are there and (I agree) it may take a year or so for them to fully develop.
I have heard discussion about possibly dealing Castro for another pitcher. If that happens, Russell would move to short (his natural position) and we would need to find a second baseman. Right now, we have a ton of pitchers on the roster and (again, I agree) the bull pen has been struggling. Hopefully getting Grim back helps that. If we could find middle relief it would be a huge step forward. We have been struggling with that for the last several years.
Yesterdays game was filled with horrible fielding, batting and pitching. Other than that, it was pretty good

However, the Cards are on fire and they are going to make one heck of a lot of teams look like that this year. Right now, it looks like we are playing for just trying to win the wild card. However, there is a slight chink in their armor. They have been using their bull pen way too much. If they wear them out, they could go on a streak where they lose quite a few they should have won.
