2013 NFL Mock Draft: 49ers could look to get better in the trenches

The San Francisco 49ers are one win away from their first Super Bowl championship since 1994, but no matter what happens there is always room to get better. For the Niners, they managed to get here with almost no help from their 2012 NFL draft class. Players like A.J. Jenkins and LaMichael James spent most of the season inactive, though James has seen more time on the field in the playoffs.

Is that trend going to continue for head coach Jim Harbaugh, or could San Francisco find an important piece on the 2013 roster when the 49ers pick either 31st or 32nd in April's draft? One player that could be of a help to them is Alabama center Barrett Jones, thinks Rob Rang of CBS Sports:

Possessing one of the league's most dominant defenses, a powerful offensive line and a dangerous dual-threat quarterback in Colin Kaepernick, the 49ers have few holes. Adding a versatile, durable swingman like Jones is a good move toward maintaining the roster's strength.

It's true that the 49ers do not have many holes, hence their run to the Super Bowl, but it is also interesting that they have those players from last years draft still on the roster. Is Jenkins expected to start contributing next year? Is James going to be the answer alongside Kendall Hunter for when Frank Gore retires? Does the team need to start looking for a replacement for Justin Smith? Or is a versatile center really the answer?

All these and more will be answered later on. San Francisco still has one more game to play before they have to think about it.
