Glad I was wrong about them.
Bell is a complete change of pace for this offense. Lamar and Gus like to smash you in the mouth as fast as possible. Bell as we know, waits for his blockers to set up and then explodes. They were interested in him a couple seasons ago before he signed with the Jets, so they must see something in him despite their running scheme.
He'll be exactly what Roman and Harbaugh want for Lamar as a check down. Not sure what the motivation is because Flacco was the worse decision making, check down throwing QB I've ever seen in my life. Giving Lamar options is one thing, but if they expect him to check it down and not run as much, I can see some frustration building. Whether that's with the fans or Lamar himself.
