Of course it has. You apparently haven't watched most of the season.
You got me. I decided to take the year off and haven't seen a game yet. Hope I haven't missed anything exciting.
Deus - Amendola and Edelman have, together, manned Welker's spot. Admittedly, without going back and rewatching games, and seeing who lined up where in which groupings, it's impossible to break down exactly who is responsible for how much production in Welker's position, and to compare that to Welker's production last season. Based on the snaps of late, Edelman has largely taken over the role, and I think you would be hard pressed to argue that we have missed Welker in light of Edelman's play.
There's about 8 million problems this team has faced this year, off the top of my head I can list the following that are far, far, far more pressing than the play at Z-WR:
- Interior OLine play has been awful at times
- OTs have been banged up, or playing poorly
- Move TE in prison
- In line TE (and 2nd best player on the whole squad) out for most of the season, now on IR
- Both starting DTs on IR
- Star LB on IR, the play of his teammates at the position has dipped in his absence
- CB1, 2 & 3 battling injuries
- SS battling injuries
In light of all that, and in light of the combined 1500 yards, 140 yards & 8TDs that Amendola and Edelman have accrued, why would you say losing Welker is the reason for what shortcomings we've had this year?
