The initial criticisms focused on the jersey tops, specifically that the letters and numbers for most teams looked comically small. Fans were first to react by comparing last year's fabrication to this year's, but players quickly jumped in too. Several anonymous players said the new jerseys looked "cheap," with one saying they looked like replicas from "T.J. Maxx." There's been frustration with the lack of customization options, thinness of material and fit. Discussion has gotten so loud that MLB felt the need to respond, with a thinly disguised press release issued this week.

But now they have potentially an even bigger issue: see through pants. 

Team photo day images and more media access have made the problem even more obvious, with some images clearly showing Nike's jersey tag through the pants fabric.
