Three things to watch:
The revolving guards. The Bucs still don't know who their starting guards will be. Time is running short to select the starters and allow them to build some chemistry with the rest of the line. Oniel Cousins, Patrick Omameh, Kadeem Edwards, Jace Daniels and Jamon Meredith each have had some work with the first team and no one has stood out in a good way. That needs to change or else the Bucs might get desperate and make a trade.
Josh McCown. The veteran quarterback didn't have a good outing in the preseason opener against Jacksonville. But most of that can be blamed on the offensive line woes. Still, McCown needs a better performance for this offense to build some confidence as it heads for the regular season.
The pass rush. The key to a Lovie Smith defense is the pass rush. There were some signs against Jacksonville that this can be a good pass rush with Michael Johnson and Adrian Clayborn on the outside and Gerald McCoy and Clinton McDonald on the inside.
