I would start Hester this week over Burlson. Hester has been fairly consistant this season and is the true number one reciever ahead of Bennett and Knox. I think the Bears will get behind in the game fairly early, causing them to go to the air often. Philly has the better pass defense, but has given up as many passing TDs as Minnesota and only allows about 20 less passing YPG.
For the flex spot, I think you are right, use one of the RBs. This one is hard to call, as Betts had looked great in the past two weeks, while Moreno has a more established role on his offense. The defensive match-up is slightly
better for Moreno, but I would say Betts is the better gamble, as he has to prove his value to the team, while Portis is still on the sidelines.
Just one man's opinion, hope this helps. I could use some help too...viewtopic.php?f=19&t=461262
