Portis to play Saturday - he doesn't seem too happy about it

[SBXVII]

I belive it's also to learn any new offenses, and......build endurance. 4 games with 4 quarters...which means starters should be playing ...IMHO....1st quarter 1st game, 2 quarters for 2nd game and so on until the last game where they should be playing or be able to play 4 quarters. but....usually the last game is to decide who stays on the team and who gets cut so basically the last game for starters is almost a waste. That leaves 3 games the starters need to build on what they have so Zorn can play the crap out of the rookies come game 4.
