Over 15 yes Ken Buchanan would win wide. Crawford would lose wide to prime Laguna as well. Crawford didn't look great at lightweight imo. Buchanan was legit brilliant in full flow and as tough as nails. I stand by my opinion that the best of Ken would beat Crawford comfortably. I will admit Crawford has went up and became far better than I thought he would after being unimpressed by him at lightweight.
I got Buchanan..who has Crawford fought that comes close to some of the guys on Buchanans resume. Way too early to talk about this fight 4 me
