For sure, they'll be a good team for some time if they can hold on to their pieces and continue to build. Solid D, Solid ST, and Harbaugh certainly proved himself. The GM certainly knew what he was doing when he picked Aldon Smith. I just don't see them winning a chip as long as they are using Alex. It takes more than his conservative play to go all the way. Indeed, they better hope Harbaugh grooms Kaepernick because they don't seem to be willing to do much else at that position. I wonder how much wear and tear Gore has, he seems to get injured easier and when he truly slows down, it will make Smith's lack of talent far more apparent. Oh, they still need a WR worth a damn as well. Crabby ain't enough.
Meanwhile we have been crafting a fantastic young D piece by piece. Some great pieces these last two drafts and with Horton's scheme completely down by the start of this season, I think that unit can be scary. Great ST play from Peterson and the top WR in the league. We get a good QB and we'll do much. Still need a compliment to Fitz, an elite pass rusher, and especially upgrades on the OL but we're getting there.
I expect games between the Cards and Niners to be damn interesting going forth.
