Why, so he can turn into Checkdown Joe, 2.0?
I think the end goal would be for Lamar to take the checkdowns more often instead of always trying to make a play when there's nothing there. He made quite a few bad decisions last season resulting in turnovers so it would be nice to see him dump the ball off more to his checkdown options.
That being said, they were planning to get the RBs more involved in the passing game last season, but then all of the injuries happened. I can completely understand why Lamar would try to force the ball downfield when his only other options were a bunch of way past-their-prime RBs with almost no juice left in the tank. Not sure if even Flacco would feel comfortable trying to dump the ball off to those guys.
