If you like Derrick Rose, you'll love Grant Hill, who played in the 90s. (Also one of the great 'men' to play in the NBA.
Players are most certainly not bigger than they used to be. Especially at Center and Power Forward. If anything they are smaller.
I would argue that they are 'better' because of the way the game is. Its the same argument with Tom Brady vs. Joe Montana. If Tom Brady had done to him what those QB's of that era had done to them, he would already be retired.
In a tougher era, those guys would flourish in todays era. Its like running a mile in a pack. Lets say you run a 8 minute mile in a 40 pound pack, but guys dont have to run in a pack today clocking 6 minute miles.
You cant just say, "Well, look at the numbers, clearly todays guys are better than past guys."
In todays game, there is defensive 3 seconds, no hand checking, no charge zones and double technicals for two guys staring at each other. This was NOT the case in 1995.
Its two completely different eras. We've taken Euro ball and Americanized it.
