I've decided I'm going to do an entire series on the NFL, whatever that may be. News in the Preseason, rankings, Mike Vick...whatever. This is the second list in the series, top 5 impact offensive rookies.

1. Adrian Peterson, RB, Minnesota. AD is the real deal. Although he's splitting carries with Chester Taylor, he should still make a big impact with an inexperienced quarterback at the helm. He should get plenty of touches, and have a nice rookie season.

2. Calvin Johnson, WR, Detroit. Johnson is big, at 6'5'', and fast, running a 4.3 40 time. The offensive mastermind himself, Mike Martz, should make Johnson a huge threat in the Lions' offense. He'll give Johnson a big role in the Detroit offense. And CJ will succeed.

3. Anthony Gonzalez, WR, Indianapolis. Although Gonzalez was not the featured receiver at Ohio State (Ted Ginn Jr.), the replacement for Brandon Stokely should have a solid rookie season. He's the better receiver although Ginn got more headlines. Plus, his QB's Peyton Manning. Why wouldn't Gonzalez have a solid year?

4. Greg Olsen, TE, Chicago. Olsen will be the solid TE QB Rex Grossman needs. Olsen, with Desmond Clark, will allow Lovie Smith to open up the offense and use two-tight end sets. Olsen is big and physical and will be a dangerous threat.

5. Marshawn Lynch, RB, Buffalo. Lynch is one of the favorites for ROY. Lynch will most likely be the starter in Buffalo so he should get plenty of touches. He is always a threat for the big play and has the makings of a perennial Pro Bowl player.
