Mark Schlabach's top 25

Now that national signing day is over, ESPN.com's Mark Schlabach revisited the top 25, factoring in the recent recruiting classes and any impact signing day might have on this season.

It's an inexact science, to be sure, but there wasn't much change as far as the ACC is concerned: No. 11 Clemson and No. 16 Florida State are still the league's only two representatives. (No, sorry, you can't count Louisville yet). In fact, Clemson dropped a few spots from No. 9.

Schlabach, like many who have seen Clemson play in recent years, isn't ready to give Clemson credit as a national title contender until there is more significant improvement on the defensive side. It's fair to expect more now that the players should be more comfortable in the second season under coordinator Brent Venables. It won't take long to find out how much improvement was made this offseason, as Clemson opens the season against Georgia. If the Tigers win that one, they should immediately validate themselves in the national title race.
