The NCAA Division I schedule kicks off this Friday, Feb. 16, which marks the unofficial start of MLB draft season as well, although some high schools and junior colleges in the south and west are already underway. This year's Rule 4 draft will take place June 4-6, with the Detroit Tigers holding the first pick, followed by the Giants, Phillies, White Sox and Reds. The class looks strong right now, the deepest overall since 2011, although the upper tier is less certain right now and heavier on the high school talent some teams have shied away from in recent drafts.
