These are just my opinion but I'd like to hear what everyone else thinks.
1. The Steelers need quality CBs beyond Ike Taylor and Cortez Allen. Teams like to attack the Steelers by air and William Gay isn't as good at NB as Cortez. Hawthorne is green and Brown is an underachiever.
2. TE: If Heath Miller is unable to start the season this will be an issue. David Paulson is very suspect as a blocker and his yang (David Johnson) is a suspect receiving TE. The Steelers can manage but not for long.
3. OL: The Steelers don't have any backups worth while outside of Beachum. If the trend continues from previous years. The Steelers are going to need some quality backups.
