Sanders does have an extremely accurate arm. Let's not act like he is void of talent and only got drafted because of his name.
So why wasn't he drafted higher and not making the two deep at a place that did not have a QB going into the season?
He is terribly flawed. He appeared to be less than focused in the draft interviews. He holds ball too long taking sacks. Many think he was focused on his stats over team needs. 75% completion rate is great but they would have won more games if he had thrown some away and had a lower completion rate.
The ball has to come out quicker, especially at a place like the Browns who have the 22nd best OL in the NFL. No way they can play a guy that holds the ball that long.
Considering all that, my question becomes, "How did he warrant being kept on the roster?"
He does possess a lot of talent, they at least think he has a chance to be good or they would not have kept him on the roster. Plus, he is cheap for a potential backup QB with upside as a possible starter someday. Add in Pickett nor Gabriel have proven to be the best either. Pickett hurt and traded now.
Browns are proving that if you got 4 QBs, you don't have one. Flacco, may still be good but he 40.
