There is no need for anyone to eat crow about Kepler. Before his recent breakout, he was well over 1,200 plate appearances of below average hitting. That's close to 2.5 seasons.
Is it great that he has broken out? Absolutely, I want to see the Twins succeed. But it's also possible, maybe likely, we would have seen earlier success from Matt Wallner had Kepler not been here. Maybe we'd be watching a revitalized Trevor Larnach instead. Maybe the Twins would have - GASP - gone and found a capable RHB to play outfield at some point in the past 18 months.
Again, it's great that Max is playing well right now but that doesn't erase literally 1,000+ plate appearances when he was actively hurting the team's offensive capabilities.
