Nobody so far has managed to defeat Islam Makhachev, but one former opponent believes he now knows the key.
Has he not watched any Islam's other fights? Oliveira tried to take him down, Volk tried 4 times, Moises tried to take him down 3 times, Arman Tsarukyan tried to take him down 12 times.
Trying to outgrapple the best grappler in the division sounds like a terrible plan.
