This a big week – and an interesting one, too — for the Browns in more ways than one, especially considering that Sunday’s regular-season opener is against the Eagles in Philadelphia.

For starters, Tuesday was the 70th anniversary of the Browns’ first regular-season game. It was Sept. 6, 1946 that the Browns crushed the Miami Seahawks 44-0 before 60,135 at Cleveland Stadium – the largest crowd ever to see a pro game anywhere to that time — in the inaugural year of the All-America Football Conference.

Wednesday was the birthday of the head coach of the Browns in that game. Paul Brown, who coached the Browns for 17 seasons, from 1946-62, was born 108 years ago, on Sept. 7, 1908, in Norwalk.

A week from Friday will mark the 66th anniversary of the Browns’ first regular-season game in the NFL. It was Sept. 16, 1950 – on a Saturday night before the rest of the league’s teams had the their openers the next afternoon – that the Browns routed the two-time defending NFL champion Eagles 35-10 at Philadelphia Municipal Stadium.

No one knew what to expect from the Browns in either of those two games. In 1946, they were a start-up team, and in 1950, they were playing in the NFL for the first time,

All these years later, no one really knows for sure what to expect from the Browns as they go into this season. The overwhelming odds are that they will struggle, particularly at first as all of their young, inexperienced players try to learn the pro game. The team, under first-year head coach Hue Jackson, is rebuilding from the ground up. In fact, it is the most extensive rebuild in Browns history. Those things take a while to do.

But while the Browns appear to be a far cry from what they were back in the day, so do the Eagles. They have a new head coach in former Browns quarterback Doug Pederson and will be starting a rookie quarterback in Carson Wentz, who is  trying to make the quantum, light-years leap from the Football Championship Subdivision to the NFL. Wentz, of course, was taken No. 2 overall in the 2016 NFL Draft with a pick obtained from the Browns in a blockbuster trade.

As such, the Eagles, who are coming off a 7-9 finish in 2016 that got head coach Chip Kelly fired with one game remaining, have tons of question marks, too. They seemingly have little or no chance of being a playoff contender.

But just after 4 p.m. Sunday, we’ll know a lot more – about both teams.
