I am on JDS for 3.5u at -141. Blagoy's boxing is decent, but he is undersized, cardio isn't very good and I am not sure he has much for power. He went 5 competetive rounds with Josh Copeland recently, with the majority of the fight playing out on the feet.
I didn't like how JDS kept backing to the cage against Stipe, but he was clearly hesitant due to Stipes size/power combo and Stipe's boxing is excellent. Blagoy doesn't have the footwork, reach (JDS 4 inch reach advantage vs 3 inch reach disadvantage to Stipe), power, etc. to have sucess doing the same. Think we are getting a pretty significant discount on JDS, this is his worst opponent in a decade.
