Team A is someone I don't know personally and he only knows one other person in our 12 team league, is friends w a mutual friend of ours and was a last second fill in to draft. He's not overly football savy from what I've gathered. His team is currently 1-5, and with 6 teams making the playoffs pretty desperate. Especially so for a WR.
He just accepted the trade his Demarco Murray for Team B's Mike Williams.
Qb (start 1)- Cam Newton, Kolb
Wr (start 3)- Jennings, Hartline, Titus Young, DHB, Greg Little
Rb (start 2)- Gore, Matthews, Demarco, Alex green
Te (start 1)- Pettigrew
Wr- Welker, Wallace, Austin, Mike Williams, Manningham
Rb- Bradshaw, Forte, Redman
Obviously it fills a hole on both teams, but imo (and im sure a few members in the league will voice their own, complicating things) he could have gotten more bang for his buck. There's no chance of collusion because Team A and B do not know each other.
edit: should also mention it's a standard scoring non ppr league
should also be mentioned that Team B is right in the middle of the playoff hunt and this obviously boosts his chances.
