I am recommending Michael Crabtree two weeks in a row. Before you click that x button in the upper right hand side of your screen, allow me to explain.
Crabtree was definitely disappointing in his last game against the Cleveland Browns, catching only four balls for 36 yards. However, he gets a fantastic matchup against the Chicago Bears' horrific defense this week, and he should be able to put up numbers similar to his game against the Baltimore Ravens this season (9 catches for 111 yards and a touchdown).
Derek Carr is finally starting to look like franchise QB material, and Crabtree is going to benefit hugely from Carr's progression throughout the entire season. He may have a big Week 4 coming, so strongly consider getting him into your fantasy football lineups.
