The San Francisco 49ers may have pulled out a win over the Seattle Seahawks in wild fashion in Week 1, but this team is still far from perfect. The lack of talent on defense could be the Achilles' heel that ruins their Super Bowl chances this season. For a team with aspirations this high, glaring weaknesses can't be swept under the rug.
If only they had a cornerback like Will Johnson on the roster.
The Arizona Cardinals' rookie proved his doubters wrong in his NFL debut, making the teams that passed on him (including the 49ers) look silly in the process.
