The 49ers have some decisions to make this offseason, not only with their own free agents, but also with some of the players they already have under contract.
Even for players under contract, there are no guarantees. Every team evaluates every player, against his scheduled salary, on a yearly basis.
Here are some of the 49ers' bigger contracts for 2013:
QB Alex Smith: The 49ers structured the three-year contract last year in such a way that they could get out of it with minimal financial harm if Smith had a bad season or Colin Kaepernick took over as the starter. Obviously, an $8.5 million salary is too much for a backup quarterback. The 49ers will likely try to trade Smith. The new league year begins March 12. The 49ers have until the end of that month to trade or release Smith. If he's still on the roster on April 1, the organization must guarantee $7.5 million of his salary.

K David Akers: It was unlikely Akers would be back at any price. But with a scheduled $3 million salary, the 49ers are expected to look for an upgrade at a discounted price. Lawrence Tynes, Shayne Graham, Nick Novak, Mike Nugent are among the scheduled free agents. They might also look toward the draft.
C Jonathan Goodwin: He enters the final year of his contract. The 49ers love to promote competition, and Daniel Kilgore and Joe Looney might get a shot to replace the veteran. Goodwin had a good season, but his scheduled $3.7 million salary makes him the highest-paid 49ers offensive lineman.
CB Carlos Rogers: He had a good season, and he figures to be part of the solution, rather than part of the problem. But he will be entering his ninth NFL season, and he's scheduled to make $5.85 million.
CB Tarell Brown: He was pretty good in 2011, in his first year as a starter. And he was better in 2012. This is the final year of his contract, and he might warrant an extension.
WR Mario Manningham: He is scheduled to make $3.95 million on the second year of his two-year contract. He underwent knee surgery and is not expected to be ready until the latter stages of training camp. When he's healthy, he figures to be back as a major contributor.
RB Frank Gore: He continues to be the main man on the 49ers' offense. He earns every penny of his $6.45 million salary.
TE Vernon Davis: His production in the passing game fell dramatically, but not enough to make the 49ers consider doing something about his $6.7 million contract for next season.
OLB Parys Haralson: He missed the entire season with a torn triceps tendon and is on pace for a full recovery for the team's offseason camps. But can the 49ers afford to pay his $2.87 million salary when Aldon Smith and Ahmad Brooks figure to play at least 90-percent of the snaps?
DT Justin Smith: He is set to earn $8 million, which seems about right for a player who -- when healthy -- is as good as there is in the NFL. After undergoing surgery to repair a 50-percent torn triceps tendon, he will undergo a rehab of approximately three months. He'll be ready to go for the regular season.
SS Donte Whitner: He and Dashon Goldson formed the hardest-hitting pair of safeties in the NFL. He is good in run support but vulnerable in pass coverage. His scheduled salary is $4.1 million.
