The optical light curve of GRB 010222 exhibited one of the slowest decays of any gamma-ray burst to date. Its broadband properties have been difficult to explain with conventional afterglow models, as they require either the power-law index of the underlying electron energy distribution to be low, p<2, or the outflow to be quasi-spherical, thus reviving the energy problem. We argue that the slow decay of GRB 010222 and a linear polarization of 1.36%±0.64% are naturally explained by a jet model with continuous energy injection. The electron energy distribution then has p=2.49±0.05, fully consistent with the expectation from detailed modeling of acceleration in relativistic shocks that p>2, thus alleviating the ``p-problem.''
