Team on the rise

USC – The Trojans’ run to the Sweet
16 in the 2007 NCAA Tournament was no one-year fluke. Coach Tim Floyd
and his staff are stockpiling the program with the kind of talent
normally reserved for elite programs. The Trojans landed the nation’s
No. 3 recruiting class for 2007, a group led by longtime prep phenom
O.J. Mayo. The Trojans have received a commitment from the No. 2
overall prospect in the class of 2008, guard Demar DeRozan from
Compton, Calif. The Trojans are also in the hunt for the No. 1-ranked
prospects from the class of 2009 and 2010, Renardo Sidney and Jeremy
Tyler. Both came to USC’s Galen Center, which opened last season, for
midnight madness. If the Trojans stay this hot on the recruiting trail,
soon there will be two powerhouse college basketball programs in Los
Angeles.
 
Best offensive player

O.J. Mayo, USC
– If the NBA hadn’t put a new age limit into place last year, Mayo
already would have played in his first NBA game by now. Instead, the
6-5 guard brings his polished game to the Trojans, who are desperate
for offense after losing three double-digit scorers (Nick Young, Gabe
Pruitt and Lodrick Stewart). A dangerous scorer, Mayo is a good outside
shooter (ignore his 4-of-17 shooting performance in the 2007 McDonald’s
All-American game) who can also attack the basket and get to the
free-throw line. Mayo, who will turn 20 before the season begins, also
has great vision and has the potential to be a good distributor.

Freshman sleeper
 

Angelo Johnson, USC – Five-star
prospects O.J. Mayo and Davon Jefferson have garnered nearly all of the
attention when it comes to UCS’s 2007 recruiting class, but Johnson
could also play a key role. The Trojans coaches were elated to learn
that the lightning-quick 5-10 point guard, who was part of the 2008
class, became eligible in September. With guard Daniel Hackett out with
a broken jaw that may force him to miss some games, Johnson may be
asked to start immediately. Even when Hackett returns, expect Johnson
to be a significant part of the rotation.

Nice breakdown of the conference.  I think the Angelo as the
"freshman sleeper" pick is spot on since he’ll see a lot of valuable PT
early with Hackett out.  Also, I see Hackett’s future at the 2/3 spot
where he can take bigger players off the dribble, which means Angelo
could very well be the starting PG come conference play.  He’ll also be
valuable defensively matching up against Darren Collison (UCLA), Tajuan
Porter (Oregon), and the rest of the quick point-guards in the
conference.
