Offseason report card for all teams

Report card time! With most of the offseason moves complete, it's time to check in and see how teams graded this offseason. My last check-in was Dec. 12, just after the crazy winter-meetings week of moves, but plenty has changed since then.

With that, here are my final offseason grades, including key additions and an explanation. I've ranked them from best grade to lowest:

1. San Diego Padres

Key additions: James Shields, Matt Kemp, Justin Upton, Wil Myers, Derek Norris, Will Middlebrooks

Padres GM A.J. Preller had perhaps the best offseason of any rookie GM in baseball history, wheeling and dealing while making San Diego not only relevant again but a serious contender for the NL West title or a wild-card berth.
