The Tigers were plagued by fitness setbacks throughout the 2016 campaign but showed plenty of spirit to eventually finish fifth in the final standings.
Boss Daryl Powell has been busy adding extra quality to his squad in recent months, with full-back Zak Hardaker and versatile forward Jesse Sene-Lefao the highlight arrivals.
However, he will also be boosted by the extra options offered by those returning from injury, including his captain Shenton, who missed almost all of this year after damaging knee ligaments in their opening game of the campaign.
The centre admits the club found shuffling their pack difficult at times last term but believes it can help spur them on to bigger and better things in 2017.
"We had about 10 out minimum every game and when we played Catalans at the end we had 13 missing," he said. "I have never seen anything like it for a team, but the boys didn't whinge about the circumstances, they just got on with it.
"Finishing fifth after what happened was a pretty special achievement and being able to do that with so many people missing should really stand us in good stead."
