In the fourth round, on the third day of the NFL draft, one of the best feel-good stories happened.

With the 131st overall pick, the San Francisco 49ers selected South Carolina running back Marcus Lattimore. He’s the kid who is recovering from his second knee surgery after suffering a particularly nasty injury last fall.

It’s a perfect spot for Lattimore. The 49ers won’t press him to play in 2013, likely keeping him on the injured reserve list while he continues to rehab and learn by watching RBs Frak Gore, Kendall Hunter and LaMichael James.

When he’s healthy, he should be a good fit for the 49ers’ system, in which lateral quickness isn’t a necessity.
