Watch for a jump from second-year tight end C.J. Fiedorowicz. The second year is big for NFL players, and both Fiedorowicz and the Texans' organization are pleased with his progress and expect a much better season out of him. His blocking was expected to be a strength, and O'Brien has indicated he thinks it will be more of one this year.
Fiedorowicz only has Garrett Graham ahead of him on the depth chart, so there is opportunity for a big jump in playing time.
