Yes, both players are in their second years. But the preseason goal with Richardson is to get him to the regular-season opener against Miami as healthy as possible, especially when you consider his injury history. The preseason goal with Weeden is to get him as much playing time as possible.
Weeden turns 30 in October, but he's still young when it comes to playing quarterback. He needs more time developing chemistry with his receivers. He needs more time in his first year in Norv Turner's offensive system. And he needs more time in a game where he can learn from mistakes and not hurt the team. It's the most meaningless game on the schedule, but Weeden can still get something out of it.
Plus, there's something to be said of going into the regular season with momentum. Weeden had a great start in the first two preseason games, leading the Browns to scores on five of six drives. Last week, he finished a deflating 12-of-25 for 105 yards. That's probably not the performance that Weeden wants to have going into games that count.
