DLH from 1997-2000 was very hard to beat. He made a fool of Trinidad and was denied the win. Mosley beat him fair and square in fight 1 (not fight 2) he had close calls with Whitaker and Quartey, but Oscar fought the best and you can't say he ducked anyone back then. At 140lb i give him every chance of beating Floyd. It would be even money at 147lb also.
How would Floyd handle Whitaker, Quartey, Trinidad and the 2000 version of Shane Mosley?
