Texans on offense: Arian Foster ran roughshod over the Bengals in his playoff debut last week, but it will be much tougher sledding this week in Baltimore. The 6-foot, 232-pound running back has an envious combination of speed and strength. Foster locates and darts through creases quickly. He has the power to break tackles at the second level but will take his share of big hits because of his upright running style. Quarterback T.J. Yates is a tough, smart, and confident rookie with a decent arm. He handles pressure well and excels in the short passing game. He lacks zip, though, and his accuracy is suspect on deep balls. Andre Johnson came back from balky hamstrings to collect five catches for 90 yards last week. He’s a tremendous receiver who is too fast for safeties and too powerful for cornerbacks.
