Ok, I'll play and make the case. The 1995 team was better vs 1995 teams than the 2015 team is vs 2015 teams. That is almost un-debatable. However over the course of the last 20 years, the game has evolved. Training methods have evolved. We have a nutritionist. The products companies make as far as weight gainer, recovery drinks, protein... are better too. As such, I would say the current team is most likely stronger and faster than the 1995 team. Teams also have far superior technology available to them. Instead of splicing film together, coaches are able to put a series of plays together on an app. Players can slow it down, rewind... They can take tablets on the bus to games. Coaches break down film riding home from the games. High school coaching has also gotten a lot better with game planning and scheme. As such, kids are starting from a higher level than they were 20 years ago. In other words, today's players have more knowledge than they did 20 years ago.
The actual game of football has changed too. Spread offenses came in. This caused a lot of reshuffling of how offenses and defenses are composed. You need a lot more speed in today's game, especially at the linebacker position. As great as Fitz was, I believe he would be too slow to play linebacker in today's game.
I would argue if you line up a top 40 2015 team, they would beat the crap out a top 10 1995 team.
