True, but there is a difference between glitches and game play limitations.
The basic game play of Tecmo Bowl was ridiculous - have defenders that were 10x faster than your WR/RB and even FASTER if they were far behind you so they could always catch up, instead of defensive plays you tried to pick the O's play and if you guessed it right it was a jail break, etc.
Could you imagine if you had to juke the same defender four times in NCAA 09 like you had to in Tecmo Bowl?
I mean it's as far from realistic as you could get BUT the game did not have large glitches. Tecmo chose to create a crazy interpretation of the NFL and executed it as intended.
