Which 3-WRs should I start on this fantasy playoff week?

That's a tough one, but based on matchups and ability I'd say start Marshall, meachem and either Chambers or Evans (flip a coin). Bryant will be up against one of the most dominant CBs in the game. Manningham isn't the #1 target with a slumping offense against a really tough divisional rival and Coles isn't an intricate part of the offense or a big deep ball threat and the vikes dont' allow much in the short field.
