I'd like to seem his back with the Cubs, but I don't think he's worth the money he's asking. He'll be 32 next season and his numbers have regressed the past two seasons.
Over his 4½ seasons with the Cubs he posted a record of 68-31 and an ERA of 2.78. Toss in two no hitters, a 5-3 post season record, and a Cy Young Award and you've got a pretty good run.
From the various brands that I collect I've ended up with 82 different Arrieta cards. The number of cards got a big bump the past two years, a combination of his Cy Young and the Cubs World Series title. In fact, 70 of the 82 cards come from 2016 and 2017. There are just two from 2014 and ten from 2015.
