It's apparent that Ravens head coach John Harbaugh won his battle with tight end Todd Heap. Harbaugh was unhappy with Heap's absences in training camp practices, and told him so. He also told Heap he had to learn how to block better.
Notice that Heap didn't get many passes thrown his way. Last week against the Texans, he had his best game ever as a blocker. He also caught some passes. Some will say that Heap got more passes because wide receiver Derrick Mason was injured, and the Ravens couldn't throw to him over the middle.
But I also think Heap has learned a lesson that was taught to him by Harbaugh and offensive coordinator Cam Cameron.
