Rob Maclean: Poor refereeing, Lee McCulloch, Rangers, Michael Devlin, Neil Lennon

Owain Fon Williams parries Scott McDonald's header but the goal was awarded

Rob Maclean continues his series assessing the main talking points from the weekend's football action.

No time for guessing games

I'm guessing that some of Scotland's leading match officials will be asked to explain themselves after a weekend of embarrassing decisions.

I'm guessing in the same way they were guessing when they were clearly unsure about major rulings in games of great significance and got them badly wrong.

When Motherwell striker Scott McDonald's header clipped the inside of the post, Inverness keeper Owain Fon Williams clawed the ball off the line. It was 2-2 at the time, a goal was given and a four-point gap between the two relegation-threatened teams is now seven.

Highland neighbours Ross County, also in the drop zone, were gifted a late penalty for one of the most blatant dives you'll ever see. They scored from the spot and the bonus point they picked up against champions Celtic could make a big difference.

Livelihoods are at stake for players and managers at the moment. This is no time for referees and assistants to play the guessing game.

Lee, Lee, more if you please

What are Kilmarnock waiting for? They should be switching Lee McCulloch's managerial appointment from temporary to permanent.

There's no need for a job application or a presentation to the board. All the evidence is out on the pitch.

Of course, they are not yet arithmetically sure of keeping their place in the Premiership but Killie are clearly heading in the right direction.

Friday night's goalless draw with Hearts, in which they were the better team, means they have taken something from nine of their last 12 games.

There's a solidity now about Kilmarnock and a healthy sprinkling of home-grown youngsters playing their part. The future looks bright and should involve McCulloch as manager.

Welcome additions to Caixinha's squad

Myles Beerman has now played three full games for Rangers

I asked a couple of weeks ago why there were no home-produced kids, other than Barrie McKay, on the first-team scene at Rangers.

Almost immediately, youngsters David Bates and Myles Beerman were pitched into the back four as an injury crisis ruled out first-choice defenders like Lee Wallace, Clint Hill and Rob Kiernan.

Neither has come through the Rangers academy. Bates was at Raith Rovers, Beerman born and brought up in Malta. But both have now played three first-team games on the bounce and 18-year-old Beerman, in particular, looks very promising.

The teenager had two years in the Manchester City youth system before heading north last summer.

Deputising for skipper Wallace, little left-back Beerman looks comfortable on the ball and great going forward. He's playing his way into Pedro Caixinha's plans.

Devlin the Accies stand-out

Hamilton captain Michael Devlin was a scoring star for his team as they boosted their battle against the drop at Dundee on Saturday.

But it's the case for the defence which will have Devlin's name on many a shopping list when the summer transfer market swings into action.

There's a serious shortage of good defenders in Scottish football - just ask Gordon Strachan - and Devlin's ability stands out.

Partick Thistle's Liam Lindsay is another young defender who'll have a chasing pack on his tail when the window opens.

And down a division, Tam O'Ware of Morton will be a wanted man as well. It'll be a big surprise if any of that talented trio start next season where they finish this one.

Perfect partnership in Leith

Hibs wanted a manager to end their top-flight exile. Neil Lennon was desperate to kick-start his career. It's been the perfect partnership.

Three years in the Championship was more than enough for Hibs. Their sizeable fan base has been screaming out for a return to the Premiership.

There are few in football who can rival Lennon's hatred of losing and he's instilled into his players the mental toughness required to grind their way to promotion.

Now comes the next challenge: to re-establish Hibs as one of Scottish football's top teams.

But not before they continue their Scottish Cup defence. And, with this season's main mission accomplished, they're dangerous opponents for semi-final favourites Aberdeen.
