All in all, the San Francisco 49ers executed a well-constructed free-agency plan for a second consecutive season.
The front office faced a daunting task in not only retaining the pieces that brought the franchise back to relevancy—but also plugging the holes that may have prevented the 49ers from ending a brilliant 2011 season on a better note.
Trent Baalke and Co. were mainly successful in re-signing their own, but a couple valuable role players did manage to slip through the cracks. Blake Costanzo and Adam Snyder were fan favorites who are unfortunately headed elsewhere this spring.
And while the low-risk, high-reward additions of Randy Moss, Brandon Jacobs and Perrish Cox are great in terms of potential—none are guarantees to make the 53-man roster—thus leaving the 49ers relatively thin at their respective positions if they can't survive training camp.
This article isn't at all to say the 49ers weren't winners in this year's free-agency period. ESPN gave the front office an "A" rating for a job well done, and I couldn't agree more.
However, there were a few faces the 49er faithful would've loved to see in red and gold this season that will instead be playing elsewhere. Peyton Manning, Mike Wallace and Brandon Carr were a couple big names that San Fran at least inquired about.
But, as they say, you can't always get what you want.
The upcoming slides will highlight four moves the front office failed to pull the trigger on that have the potential to haunt the team moving forward.
