Tech is absolutely horrible on the PS3. I've been playing online with them and getting crushed. On my old PS2, I have played head to head with friends (not online) who were playing with Top 5 teams and I've beaten them badly with Tech. Apparently, the online play is a bit tougher... I decided to switch over and use Boise State (ranked #23 on NCAA 08) just to see if it was me or if I was getting killed because of the poor ranking given Tech. Well, I beat one of the top-rated online players who was using Michigan -- 50-23. That's the first time I've used a team other than Tech since I started playing on the old PS1...
I showered immediately afterward, btw.
