Where does the article say (or anyone) say that Lowrie won't get a shot at the SS position? That's what i don't get.
I see perfect logic in Tito viewing Lowrie as the utility man, and i'll detail the reasons.
First, let's establish this: Lowrie is a better utility player than Scutaro because he can play first base and has a better arm (Scutaro's arm is accurate but weak) for playing third.
Seeing as the entire infield is coming off surgery/injury, what about any of these scenarios:
1) Gonzales is not on spot to start the season, Lowrie plays first.
2) Pedroia has problems with his foot, Lowrie plays second.
3) He outperforms Scutaro by a wide margin or he is injured, Lowrie plays short.
4) Youkilis has problems with his thumb, Lowrie plays third.
All of the above are likely possibilities, and all four of those guys will likely be rested regularly throughout the season, giving Lowrie ample opportunities to play, and making his ability to play around the infield much more valuable to the team (in the case that there are complications).
If he's meant to be the regular shortstop, he'll earn it, but in the meantime, there are so many question marks that his versatility is extremely important.
I've said this before, but the most underrrated aspect of baseball is a deep bench, and having a guy who can produce at any IF position is golden.
