Five things we learned when the Lions beat the Vikings 34-24 in the season opener on Sunday at Ford Field.

1. Reggie Bush is worth every cent of $4 million per year. He’s a perfect fit in this offense and it showed. No breaking in, Bush is comfortable already. He changes the offense big-time. Not just his yardage (101 receiving, 90 rushing) but just his presence will open up the field for Calvin Johnson and the other receivers.

2. Nothing is wrong with Matthew Stafford. Mechanics, schemanics. He can move the offense. Period. He had a great camp. For those who were watching Sunday’s game is not a surprise.

3. The defensive line is deep and it delivered that includes first-round pick Ziggy Ansah.

4. They are not the same old Lions. Those Lions would’ve faded at half-time or before then. These guys just righted the ship.

5. It’s just one game, so no reason to get too excited. They haven’t won a game since Nov. 4 (at Jacksonville) so understandably fans are going to savor this one. The thing is they have the horses and now apparently they have the right attitude to get it done. It wasn’t perfect. The first half was sloppy, still too many penalties. But they found a way to win and there’s something to like about that.
