Task: Question Answering
Input (English): Passage: This was the Browns' first home opener win since 2004, and also marked Johnny Manziel's NFL debut. The defense, primarily by rotating DB's Tashaun Gipson, Buster Skrine, rookie Justin Gilbert and Joe Haden, were able to neutralize TE Jimmy Graham and QB Drew Brees for almost the entire first half.

Question: How many NFL games has Manziel won?
