I'm a Lions fan and I have a little insight in to this. Lions went 0-16 in 2008. They drafted Stafford #1 and they went 2-14 in his rookie year, which he went 2-8 and missed 6 games. We did get blown out quite a few times, but it was a big step forward from the 2008 team. In 2010 Stafford only played 3 games, but he had 6tds and 1int in those games. The Lions went 6-10 and lost a lot of games that were close. The third year after 0-16, Stafford played his first full season. We won 10 games and made the playoffs the first time in 12 seasons. Stafford had 5000 yards and 40tds. So basically we went 2-14, 6-10, 10-6 after going 0-16. Depending on how the Browns finish this year will tell if progress really has been made. I'd say 4-12 would be a natural progression where you can say ok we improved.
Good game today by the way. I know I was dreading this game, as nobody wants to be the team to lose to a team without a win. Lions had a big game last week winning in Lambeau for the second time in 28 seasons. We were in a short week and came out flat for sure. The Lions in my opinion played one of their worse games today. The Browns are desperate and have nothing to lose, nobody wants to play a team like that. I will give up to Browns coaches a little bit, they came out with a great game plan and those first scripted plays were executed really well. Kizer played his best game perhaps.
Good Luck the rest of the way.
