Why is the normally reliable Jay Bruce struggling so far? Plus Lyle Overbay, Juan Nicasio, Allen Craig and Francisco Liriano.

Can Andrew Cashner build on his impressive finish last season? Plus Nolan Arenado, A.J. Pollock, Anthony Rendon and Kyle Kendrick.

Will Coors Field help Justin Morneau reach 20 HRs again? Plus Johnny Cueto, Matt Garza, Russell Martin and Seth Smith.

Is Jason Grilli among the NL's elite closers? Plus Junior Lake, Jorge de la Rosa, Angel Pagan and Carlos Ruiz.

Brandon Phillips has been one of the NL's steadiest performers at second base. At 33, can he be counted on for another year of the same production? Plus Andre Ethier, Kyle Lohse, Wandy Rodriguez and Peter Bourjos.

B.J. Upton went from potential breakout to bust in a year's time. Can we expect him to recover? Plus Khris Davis, Brett Anderson, Aramis Ramirez and Bartolo Colon.

Everth Cabrera was on track to eclipse his 2012 stolen base total last summer when a wrench was thrown into those plans. Plus Greinke, Romo, Revere and G. Jones.

Pedro Alvarez is one of two NL hitters to connect for 30 HRs each of the past two seasons. But there remains a significant obstacle to further offensive value.

Yes, there was a DL trip for Troy Tulowitzki, but he rebounded from an injury-plagued 2012 and remained an elite SS choice. But nearing age 30, are there any signs of decline?

Matt Carpenter was a popular sleeper choice headed into drafts last spring, and those owners who picked up the versatile infielder were rewarded justly. Plus Gomez, Delgado, Wacha and Barney.

Allen Craig began with a homer-less April and endured another drought in July. So the skills support the 25-plus HRs we expected a year ago, or is last year a sign of things to come?
