well you are certainly entitled to your opinion. But Maclin isn't better than manningham. Besides week 2, maclin has 6 receptions total, and now has no QB
Mcfadden is the leading fantasy RB, and a focal point of his offense with no real competition
Stafford is pretty even with Brees IMO. Not really a big enough difference in value to call it much more than a toss up, you can argue staffords health, but injuries are always a shit shoot.
Also, why propose this Qb-RB-WR for QB-RB-WR trade if all 3 of your players are supposedly better?
Anyway you may be correct and all 3 of your players may end up scoring more pts the remaining weeks, but fosters health/possible workload sharing makes this way too mcuh of a risk to do, which is why his value is lower
