Neither opponents of both boxers are impressive. However, this is a stylistic nightmare for Garcia.
Garcia better have that snap like his camp is saying or Spence will go terminator on him and this fight will be over before the beer is done.
To beat Spence you need better speed and reflexes. Garcia might be faster but it isn't that far from Spence.
Spence by 7 rd TKO.
If this fight goes the distance no way Garcia loses.
