As for Smoak, his quality of contact suggests his .208 batting average and .406 slugging percentage are much too low. StatCast expected a .245 batting average, which is his career average. For slugging, StatCast expected a .476 mark, not far off of his career average. With his career high 15.8 percent walk rate, Smoak should've had a .367 wOBA. That's a whopping 40 points higher than his actual wOBA.
To put that in perspective, his expected rates put him in the neighborhood of the actual results of Bryce Harper and Joc Pederson. But his surface numbers put him more in the production range of big disappointments like Paul DeJong and Dexter Fowler. Sure, they're about league average. But Smoak is a well above league average hitter.
It's likely no surprise that people aren't too excited about Justin Smoak rookie cards. He also doesn't have a Bowman Chrome Auto, which makes his card market a little harder to gauge relative to his peers. His top rookie autos are several 2008 Razor cards and 2008 Upper Deck Team USA. Of course, the Upper Deck cards are more sought after. For base rookie card, there are the serial numbered 2010 eTopps and 2011 Topps rookie card.
Because of his poor surface numbers, particular Smoak rookie cards don't sell that consistently. But if you are looking for one card to target, it would be colored refractors of his 2011 Topps RC as that is the card targeted most consistently.
A strong 30 HR and 100 RBI could still be in Smoak's future. The big question is who he plays for in 2020. A big market will certainly help Smoak cards. What do you see in the cards (pun intended) for Justin Smoak's future?
