What is Eagles Ernie Sims so mad about?

We know that Philadelphia Eagles LB Ernie Sims is happy to be out of Detroit and playing for the Lions, but what is he so mad about? Sims has been a very aggressive player for the Eagles during their off season and especially recently in training camp with pads on. The Eagles coaches love his passion but perhaps they’d like to see him ease up just a bit on his own teammates. Eagles defensive coordinator, Sean McDermott loves his passion as well but told reporters on Monday, “I love his attitude…but we have to know how to practice together and take care of each other”. Sims apparently laid out Eagles TE Brent Celek as he was going across the middle for a pass reception. I love the passion, but dammit man, let’s save the offensive players for the games. We don’t need to be taking them out in practice.
