Plain and simple: The Cleveland Indians have a lot of what selling teams need.

According to Peter Gammons of the Gammonsdaily.com, the Tribe's farm system is far from wilting and seven players could be the reason why the phone keeps ringing.

"What has been interesting is the number of teams that have come to them, because their system may be the most underappreciated, with 7 of the so-called top 100 prospects in the game, from outfielders Clint Frazier and Bradley Zimmer to first base slugger Bobby Bradley to pitchers Mike Clevinger, Justus Sheffield and Brady Aiken to 21-year-old catcher Francisco Mejia and Cuban third baseman Yandy Diaz," writes Gammons.

Gammons also went on to quote one NL GM hinting at the recent phone history for the Indians.

"The Indians may have the most underrated farm system in the game," the GM said. "They are taking a lot of calls right now. If a team is selling, they will call Cleveland."

That said, if you feel like you've been hearing Cleveland pop up into nearly every trade conversation, now you know why.
