Thining this one over again, Lynch could well have a good style to defuse Chang. A bit bigger, harder hitting and stronger, with his own awkward explosiveness and unpredictability.I could see him forcing Chang to do a bit too much moving and while punches landed might be quite equal, Lynch will be seen to be dictating the pace more and looking less ragged in the clinch\inside.
Equally fast-footed unorthodox wide-punching hard-punching Lynch is a very hard fight for swarming Chang. I'd say compact-style counterpunching defensively-oriented Canto has better chances to win against Lynch.
