Collusion or just a bad trade? Need outside opinions

So this past week there was a trade made between the 5th ranked team (8-5) and 9th ranked team (4-6-3). #9 is three wins out from the last play-off spot with 6 weeks left. #5 has five goalies on his roster and none of them are great. #9 has two pretty good goalies but is lacking on D. Our league settings: 12 teams made up of 3 RW, 3C, 3LW, 5D, 2G and 5 Bench with 2 IR spots. We have G, A, ATOI, Shots, Blocks, Hits, +/-, Special Teams Points, Wins, GAA and SV%. Top 6 teams make the play-offs.

5 traded Talbot (Edm, G) and Tanev (Van, D) for 9's Lundqvist (NYR, G). This caused an uproar from three owners, and the two loudest about the trade are #1 and #2 overall.

Here are the stats to look at:

Season Stats:

Player | GS| Wins| GA| SV| Min| GAA| SV%| ---|---|----|----|----|----|----|----|----|----|---- Lundqvist | 33 | 18 | 84| 942| 1986| 2.54 | .918 | Talbot | 21| 7 | 59 | 591 | 1274 | 2.78 | .909 |

Player | G | A | +/- | ATOI | SOG | HIT | BLK | STP ---|---|----|----|----|----|----|----|----|----|---- Tanev | 2 | 6 | 2 | 21:32 | 22 | 13 | 98 | 1

I looked into it because of possible collusion. At first I believed it was collusion, until it was pointed out to me that the goalies' recent stats are far different from their season long stats. In fact, I was against the Lundqvist owner this week and the only reason he played Lundqvist was because he needed to get to the minimum 3 goalie starts.

Last 30 Days Stats:

Player | GS| Wins| GA| SV| Min| GAA| SV%| ---|---|----|----|----|----|----|----|----|----|---- Lundqvist | 10 | 4 | 38 | 255 | 602| 3.78 | .870 | Talbot | 9| 4 | 20 | 280 | 535 | 2.24 | .933 |

After seeing that I realized he was most likely panicking and selling Lundqvist off and the other owner was just buying him cheap. Taking name value out of the equation, it's not the best trade, but it could be seen as #9 making a big move in hopes of getting some good goalie play now. He can't really wait for Lundqvist to right the ship as he needs to be winning all the weeks he can in order to give himself a shot at the play-offs. #9's other goalie is Varlamov. I let the trade go through as after taking a look at it, it didn't look like collusion to me. In fact, #5 had offered three players for Lundqvist but #9 turned it down due to not enough roster room. What are your opinions? Just a dumb trade or collusion?

Further stuff: Now that the trade went through, #2 overall (and last year's winner) approached me and has said he's out and that I can set his line-up for him. This is a league where there had been a total of 1 trade before this, so I feel like too much regulation will damper future trading.
