University of Iowa tight end Dallas Clark enters this season as one of the most experienced pass catchers for the Hawkeyes. He says being a leader doesn’t put more pressure on him, just an opportunity to help the offense.The junior from Livermore, Iowa caught 38 passes and scored four touchdowns last season. Coach Kirk Ferentz calls Clark one of the best tight ends in the conference, and in the country. Clark says that’s high praise, because he respects Ferentz. He says the young receivers have made some strides already in their work this summer. Clark walked on at Iowa after staring in high school at Twin River Valley, but not enough to draw the attention of big-time schools. He said the rise from walk-on to star gives him a unique perspective on those who’re trying to do the same thing. He says he sees them differently as he never had all the attention of being recruited. Clark says walk-ons have the same scared look he had, and he says he tries to help them learn the system.Iowa opens the season August 31st against Akron.
