Over 10 and as crude as he was, I can see Layne edging Tua, outboxing him, manouvering to turn him, grab, clinch, then outjab and clinch again, etc. But of course, there is always the possibility for Tua to catch him with a heymaker. 15 rounds would give Tua even more chances to do so.
Tua launches him into the third row. Faster, sttonger,bigger, much harder puncher, better boxer, better output...
