1. Town have genuine competition for the goalkeeper's shirt.
A back injury for Alex Smithies suffered in training but kept quiet during the derby build-up paved the way for Joe Murphy's league bow, and the 33-year-old summer signing from Coventry City responded with a bright and brave performance and a clean sheet preserved by a fine late save from Royston Drenthe.
2. Old-style physical centre-forward play isn't dead.
At least, it seems, in the eyes of referee Graham Salisbury, who saw little wrong with a number of robust challenges on Murphy by Sheffield Wednesday's Stevie May, the first of which left the keeper winded and with shoulder pain and in need of a few minutes of treatment. May was eventually yellow carded, but for a foul on Joel Lynch.
3. Sean Scannell can expect some special attention.
The winger's bright form, rewarded by last week's new contract, has been noted outside Huddersfield. Wednesday were the latest side to multiple mark the 24-year-old, who had an absorbing tussle with left-back Jeremy Helan. Stuart Gray's team also did good containing jobs on Harry Bunn and Grant Holt.
4. Town are becoming pleasingly hard to beat at home.
It's now six unbeaten (three wins and three draws) and consecutive clean sheets for Chris Powell's side at the John Smith's Stadium, where Town had a dismal record before the current manager's arrival.
They got a break when May hit both bar and post with one shot, but as the saying goes, you make your own luck.
5. Always play to the whistle.
Town substitute Nahki Wells seemed to hesitate and look for an offside flag when he found himself in a great position late on. Wednesday keeper Keiren Westwood saved - did the home man's delay help him? It would probably been better had Wells done what comes so naturally to him by putting the ball in the net, then looked at the assistant referee!
