Week 4 of the Page 2 Fantasy Football Challenge is upon us. Each week, a guest picker chooses a quarterback, wide receiver and running back. The only players off-limits are those selected by the previous week's guest picker. The guest -- Twins outfielder Denard Span, despite Trevor Plouffe's protest of Span's fantasy knowledge -- will go head-to-head against Star Tribune writer Michael Rand, who is not allowed to pick anyone ranked in the top 10 by NFL.com experts at their respective positions:DENARD SPAN'S WEEK 4 FANTASY PICKS
QB: Aaron Rodgers, Packers
NFL.com fantasy QB rank: No. 1. Matchup: Saints
Well, he was my first-round pick, No. 1 overall in my league, so you can't go wrong with Aaron Rodgers. (Note: This pick was made before the MNF fiasco gave Rodgers extra motivation).
WR: Calvin Johnson, Lions
NFL.com fantasy WR rank: No. 1
Matchup: Vikings
Have to go with Megatron. I know his quarterback, Matthew Stafford, has some injury concerns, but I'm not too worried. He's a guy who can put up some big numbers.
RB: Jamaal Charles, Chiefs
