Here are five things we learned from the Lions’ 24-6 preseason loss to the Cleveland Browns on Thursday night. 

1. Reggie Bush was the highlight on offense with five catches and eight rushes. With Calvin Johnson sidelined as a precaution with a knee bruise, this is not the offense we’ll normally see. But it gave Bush a chance to get a little more comfortable in the offense. He and Stafford have to develop a rapport and Thursday night was a good chance to develop that. Bush was called for a personal foul. Even though he got caught retaliating, it was still inexcusable.

2. The secondary needs to work on tackling. Thought they had too many missed tackles in the first preseason game — a win over the Jets. But they had more in Cleveland. This should be a problem that is fixable. Yes, the defense was playing without safety Louis Delmas but that is no excuse.

3. It looked like there might have been a lack of communication between the linebackers and safeties. If so, it’s another correctable problem. But it must be fixed.

4. The offense has scored just one touchdown in the first two games — a Shaun Hill pass to Matt Willis in win over the Jets. This is not good, of course. But wouldn’t be too concerned just yet. More than touchdowns, Matthew Stafford needs to keep the guys on the field by making first downs. He said that the problem at Cleveland was two-fold — the offense couldn’t stay on the field (their first three possessions were three-and-outs) and they had a lack of explosive plays. Wide receivers Matt Willis and Terrence Austin had good games playing with Shaun Hill.

5. The defensive line is all of that. Ndamukong Suh and Nick Fairley played really well if you don’t count Suh’s personal foul for roughing the passer. Ziggy Ansah started at right defensive end and Jason Jones was on the left side. a good game by both — no flashy plays like in week one.
