Cleveland Indians organization discussion

I am now working on the New York Mets Top 20 Prospects for 2016 list. The next team in line is the Cleveland Indians, to be followed by the Milwaukee Brewers, Boston Red Sox, Los Angeles Dodgers, Oakland Athletics, and the Miami Marlins.

Use this thread to discuss the Cleveland Indians farm system and organization. Possible points of discussion include, but are certainly not limited to,

***How good can Francisco Lindor really be? Is it possible he could develop even more power than he showed in 2015? Or is what-we-see-what-we-get, keeping in mind that what we already have is a truly outstanding player.

***True or False: Giovanny Urshela will be an above-average hitter someday.

***Who do you like better among the outfielders, Bradley Zimmer or Clint Frazier?

***I think the Indians did very well picking up Rob Kaminsky from the Cardinals over the summer for Brandon Moss, but perhaps that is because I think Kaminsky can remain a starter. Some experts believe he'll be a reliever down the line. What do you think?

***My surface impression is that this is an under-rated system. Agree or disagree?

***As always, feel free to share your sleepers, overlooked, underrated or overrated prospects.
