They targeted Schwartz early and signed him as soon as free agency began. They viewed him not as a cure-all but as a foundation piece -- a reliable veteran whose presence at left guard would help make the rest of their line problems easier to solve.
So while injuries happen and you can't fault the Giants if Schwartz's toe injury keeps him out for a significant period of time, it is a major problem for them, and they may struggle more than you think to solve it.
The "next man up," to borrow from strained NFL parlance, is rookie Weston Richburg, a second-round pick who played center in college but has been working throughout camp at guard behind Schwartz and Brandon Mosley. Richburg obviously has talent. There was some thought when he was drafted that he might be a better option at center than current projected starter J.D. Walton. But he's also a rookie, and even he admits he's not where he'd like to be at this point in his development.
"Oh, no," Richburg said Sunday morning. "If you're content with how you're playing, I think you're cheating yourself. I always want to get better. I made some mistakes in the last game that I know I need to correct."
He may have no choice but to correct them on the fly. The Giants don't like to lean on rookies as starters, but they showed last season with right tackle Justin Pugh that they will if they have no other choice. Pugh played well enough as a 16-game rookie starter that it worked out. Problem is, there's no guarantee that it will work out again. Even if Richburg is an eventual Pro Bowler, no one can be sure he'll develop as quickly as Pugh did.
"What I'm doing best right now is having a short memory," Richburg said. "If I make a mistake, just clap it off and go on to the next play and not let it affect me. I think I'm doing a good job of forgetting about it and just playing fast and continuing."
Great, but the issue is that the understandable rookie mistakes are happening, and that mistakes on the offensive line are hazardous to the health and effectiveness of Giants quarterback Eli Manning. This wouldn't be as serious a concern if left guard were the only spot at which there was concern. But the Giants have had pass-protection issues with Walton, Mosley and left tackle Will Beatty this preseason as well. Adding a still-green Richburg to the starting mix leaves Pugh as the surest commodity, and even he is a second-year player whose growing pains likely aren't all the way behind him. There are still talent evaluators around the league who view Pugh as a guard playing out of position and think the Giants' line will be better once he's moved inside, but at this point they don't have any better options at tackle.
No, the issue here continues to be depth, and that's a failing of the organization's offseason. They brought in John Jerry on the premise that he'd be a quality veteran backup should something happen at guard, yet after Chris Snee retired and Schwartz got hurt Jerry remains in a backup role while Richburg and Mosley line up with the starters. Charles Brown, signed as the veteran depth at tackle, played terribly in relief of Beatty early and is now hurt, which has resulted in Pugh having to take some left tackle snaps in practice with Mosley moved out to right tackle. Reserve guard/center Eric Herman is suspended for four games, and reserve guard/tackle James Brewer is hurt.
It's thin, folks, and it's still very thin at the interior positions that were supposed to be upgraded this year. There's a lot of book from last year on how easy and effective it is to pressure Manning from the A-gap, and if the Giants don't get things figured out in there, defenses aren't going to need to alter last year's plan very much to beat them. After all the work that was done in the offseason, the Giants' biggest 2014 problem may end up being exactly the same as the one that sunk them in 2013.
