A Richmond premiership in the next few years would prompt Trent Cotchin to consider retirement, even if only in his mid-20s.

While determined to help shape the Tigers into a successful side and close to signing a new contract, Cotchin has spoken candidly of the enormous physical effort it takes to play in the AFL, and his doubts that his body will be up to a long career.

The 23-year-old was challenged by injury during his first few years at Richmond, an experience that made him think more about the life he wanted to build outside football, and he has never really enjoyed the all-consuming nature of the football scene.

''I love footy and I love how it challenges you in some way, every single day. I love trying to help the team any way I can and I love how it helps you meet people and learn all sorts of things you wouldn't have been exposed to,'' Cotchin said. ''But I'm looking forward to it being over as well. I reckon if we won a premiership in the next three years I'd pretty much be done.''
