Their most notable moves apart from that were completed in February.
Where that leaves the squad for the coming months remains to be seen but the month and a bit pretty much ran as had been outlined by Paul Barber in an interview with The Argus midway through.
The Albion chief executive and deputy chairman said the main incoming business was done early with Pascal Gross.
He said there would be one or two departures and that the club were understanding of Diego Coppola’s desire for game time but would only let him go on loan if they had enough resources in defence.
The two moves which did not quite fit into the update we were given a little more than two weeks ago were last day loan changes.
Matt O’Riley coming back from a Marseille outfit suddenly needing to rethink after European elimination.
And Brajan Gruda’s switch to Leipzig looking for more game time and possibly a late push for the World Cup.
The hope will be Gruda and Coppola can both benefit from their loans in the longer term.
The same will go for Evan Ferguson at Roma once he is over his current ankle injury.
Remember Alexis Mac Allister, Moises Caicedo, Jan Paul van Hecke all benefited from loans after joining the Seagulls.
But, when a team are struggling for wins, the transfer window can be seen as a quick fix or pick-me-up.
And it seems the fact that did happen late in the window was a disappointment for many fans who voiced opinions via social media or platforms such as our comments facility online.
The perennial wish at this time of year seems to be for a ready-made striker.
That has only happened once since Glenn Murray arrived from Rochdale for £300,000 in 2008.
And that was when Leo Ulloa moved from Almeria in 2013.
But even he was signed six months late, as he awaited an EU passport, and that delay probably cost Albion automatic promotion.
How much you have to spend to sign a Prem striker at this time of year was underlined by Crystal Palace paying about £50 million for Jorgen Strand Larsen.
Otherwise, you are looking at a project from overseas or a lower division.
The sort of project who might take longer to settle in than it takes Stefanos Tzimas to recover from injury.
So signing a striker, certainly for immediate use, never felt likely.
Elsewhere it was easy to consider Gruda and O’Riley almost as a swap deal given one left as the other arrived.
Gruda’s departure weakens Albion on the right but is he really a wide player anyway?
Not according to Leipzig, who see him as an attacking midfielder or No.10.
Maybe it takes away the tempation to play him there.
What Albion really need is a fully-fit double threat of Kaoru Mitoma and Yankuba Minteh, something they have not really had since late September.
When Minteh is not on the pitch, one wonders what happens now on the right. Diego Gomez looks the most likely option.
The glasses of many Albion followers are half-empty at the moment but, if they were half-full, you could wonder what Gruda's exit says about what the club feel they can get for the rest of the season from Harry Howell and (fingers crossed, touch wood, no pressure) Solly March. Or is that too optimistic?
Gross was the big news in midfield and Albion have already had almost five weeks of benefit from him since news of his arrival leaked as the first drinks were being sipped on New Year's Eve
Elsewhere in midfield, it is worthy of note that Carlos Baleba never got a mention on deadline day.
At the back, Igor for Coppola can be a positive if it allows the latter scope to develop.
It still feels like a right-back will be added in the summer.
And there was another point of note - the number of loans which were either cut short or changed.
What that says about the initial moves or the progress (or otherwise) of players concerned can be debated.
There may well be different reasons, different circumstances. But it was an unusually high number and there are one two already reaping benefits.
Ironically, the player who was most regularly linked with a change of loan - Ferguson at Roma - stayed where he was.
Given that he did not even do pre-season with the Albion squad, it would have been a big step to bring him back. He can make strides in Italy.
But the striker resources will be the talking point and fingers will be crossed that Danny Welbeck avoids injury.
There is certainly a Gross profit from the winter window.
Albion will have to keep spreading the goals around to ensure there is a net gain.
It was unrealistic to expect anything different.
