Five much less obvious areas of concern as the Eagles convene at Lehigh:
1 What form will Donovan McNabb's touchdown-dance tribute to Michael Jackson take?
In recent years, No. 5 has often seemed to be the only athlete willing to risk looking uncool enough to evoke something as old-school as "Thriller." Now he has plenty of company. Can McNabb raise his game?
2 Can Reggie Brown revive his Eagles career, or is he this summer's Jerome McDougle?
In minicamps, Brown looked like a man determined to recapture the promise of his first two Eagles seasons. Unfortunately, he's swimming in a deeper wideout pool than the Birds have seen in the Andy Reid era. Like McDougle a year ago, Reggie might have waited too long to start to turn it around.
