Meh, let it play out.
I understand why people hate the Justin Smoak thing, but obviously the Jays think there is something there. I'm not sure what it is, but they have a lot more information than us.
Someone like Angel Pagan doesn't move the needle much for this roster. Having moving parts is a pretty good thing for a baseball team. Right now Pearce could end up at 1st or left field. If Pompey breaks out or Upton looks productive while Smoak sucks again, then Pearce is the 1B. If Smoak turns into a useful player then Pearce can play left. Let's see what happens.
The time to call for Smoakie being cut was back when viable starters were still available in free agency - guys like Valbuena, Napoli, Moss. That's just not the situation anymore; Pagan is 35/36 and does not project well.
