The San Francisco 49ers suffered a deflating 26-21 defeat to the Jacksonville Jaguars in their Week 4 matchup at Levi's Stadium.
Most things went wrong for the Niners in that game, but through all that, they were still in the game until the bitter end.
That said, they'll need to address a few areas ahead of Week 5.
Since the 49ers play in Week 5 against the Los Angeles Rams on Thursday Night Football, they'll have a short week to address some of those areas. and there are three main ones the Niners need to address ahead of TNF if they hope to defeat the LA.
