umm.....to put it simply.....NO
No college team is better than any NFL team, period...not even close...nor has there been a college team that could beat an NFL team in the last 30+ years...period.......not even close.
Az-Hakim was a better Steve Breaston in college - Charles Rodgers, the Lions top receiver, is much better than Braylon Edwards, and the Michigan O-line, while solid, isn't as good/big/strong as the Lions O-lineman are...Harrington is way better than Navarre too.....now, Chris Perry might step in next year and be a good NFL running back, but Olandis Gary, who you seemingly like to rip on, has already been a 1000 yard rusher in the NFL - and don't forget James Stewart, who has been an all-pro NFL player, though he is currently injured.
The size/speed/strength difference is WAY too much from an NCAA team to an NFL team - any team. DB's in the NFL would, for the most part, lock up NCAA receivers like they were little kids - seriously, they would have trouble just getting off the line of scrimmage - I'm not saying the Michigan receivers aren't going to be good NFL players (actually only Edwards likely will - Breaston is, like I said, another Hakim-type player, more impact in the return game), but they aren't NFL players now, and without a few more years of working out and playing against NFL competition, they wouldn't stand a chance. Same goes for NCAA offensive lineman - Michigan has a big group, though no superstars, but they would be at a loss against the speed of an NFL pass rush. Navarre reading an NFL team's defenses? Good luck with that.
Oklahoma against an NFL team? Please - if Baylor can get for sacks against OU, what is an NFL team going to do? White wouldn't make it out of the first quarter.
Miami's (FL) offense last year is probably the most talented offensive unit, in terms of being pro-ready, that I've seen - if McKinney (vikings left tackle) had stayed for his Sr year and played on that team, I would at least grant you that team would be able to score some points against an NFL team - Andre Johnson, Kellen Winslow Jr, McGehee (healthy!), 4 NFL O lineman, but even that is questionable.
