In what ways have Quintana and Hendricks been better than Archer this year? They have slightly better ERAs...but all the underlying metrics point to Archer being the far superior pitcher in 2018. I'm not saying the Cubs should necessarily give up Happ in a deal for Archer--I'm pretty apprehensive since he missed time with an arm injury this year. But really, comparing Archer's performance this year to the performance of Cubs pitchers is a good argument in favor of making a strong offer.
