The nib Newcastle Knights are blessed with options for 2019.
In the lead-up to the new season, newcastleknights.com.au will look over the depth of the Club and break down the positional options at the disposal of coach Nathan Brown.
This week we take a look at the lock possibilities.
In 24 appearances in 2018, Guerra featured at lock 11 times.
He's an experienced leader and it was evident when he was awarded the Gladiator and Coaches awards at the Danny Buderus Medal night.
You can put Guerra in the backrow or lock and he'll give you 100 percent effort in both attack and defence.
Guerra has played plenty of lock throughout his career and would be a very reliable option for Coach Nathan Brown.
What do the boys want for Christmas?
Barnett has probably played his best football at lock in his 56-game career.
Like Guerra, he can play either second-row or lock.
Barnett started the 2018 season at lock and performed well there in the early rounds before being shifted to second-row.
He's a solid middle defender, finishing the 2018 season with 681 tackles.
Glasby has played most of his NRL career in the front-row but is very capable of playing lock if needed.
He's a solid defender and a workhorse in the middle of the field.
He is a reliable option for Brown to start at lock because you know exactly what you're going to get from him.
Glasby: The enthusiasm is inspiring
Brown experimented with Ese'ese at lock in 2018 and he didn't look out of place.
The 24-year-old has mainly played in the front-row in his young career but could feature more at lock in 2019.
He's a hard-running forward and always takes some stopping from the opposition defence.
The first couple of days have been really special
He's more likely to start the 2019 wearing the no.10 jersey, but Klemmer is still an option for Brown to play at the back of the scrum.
He's a very experienced forward who has played plenty of games at lock.
