Given the limitation to only consider the TD scoring:
I see CJ as slightly more valuable than Harrison but not because of the injury situation. I could argue in favor of either of them over the rest of the season, but I like CJ's week 16 matchup vs Cleveland better than Harrison's matchup vs Houston. For that reason alone, I'd rather have CJ. Slight advantage to Team A here.
Bulger may be hurt right now, but I still have to believe with upcoming games (week in brackets) against Cleveland(8), New Orleans(10), Frisco(11), Atlanta(13), Cincy (14) & Green Bay (15), he is going to score several TD's so he could score as many points in a TD only format as Lynch does, in my opinion. (The Rams have 5 passing TD's in 5 games and Lynch has 3 rushing TD's in 5 games.)
Jackson has limited value. Who does Team A cut to make room for Jackson?
Team A probably gets the better deal here, but I can't say the exchange in value is absurd at all.
If team B has Brady, Palmer, or somebody like that at QB, and no RB's then I might question what value Bulger would bring to his team to justify trading away Lynch. While a situation like that would not be evidence of collusion, it would be enough for me to dig deeper into the reasoning for the trade and look for evidence of collusion. Otherwise let it go.
