I don't think anyone isn't excited about the new guys, but it's not either/or. Expecting a pair of freshman to step right up and immediately replace two experienced upper classmen is asking a lot, to say the least.
I'm perfectly willing to believe that Odomes and James have higher ceilings than Booker and Hornbeak, but will they be better as true freshmen than Hornbeak and Booker would have been as a senior and a junior, respectively? That's doubtful. If they are, I'll be thrilled, but also very surprised.
You're right, there is no substitute for experience. Thus, it would be foolish to expect our two freshmen to be as good from the get-go as Booker and Hornbeak might have been if they had stayed for their junior seasons.
Having said all of that, I think it's reasonable to assume that Odomes and James have the potential to be at least as good as Booker and Hornbeak were as freshmen. Both of those players logged quality minutes their first season, which is essentially what I think we can expect from Odomes and James (assuming his recovery is complete and he is able to go full speed this fall).
While I was a big time supporter of Je'lon and Frank. Both players were slowed by injuries their second season. But the fact remains that they did not put up earth shattering numbers at any point of their career at OU.
Je'lon's best season was as a freshmen, when he saw action in all 32 games and made 29 starts (first 20 and final nine)... Averaged 5.6 points, 2.7 rebounds, 1.7 assists and 1.0 steal in 22.7 minutes per game... Shot .374 from field, .333 from 3-point range (25-for-75) and .739 from free throw line. Hampered by a foot injury his sophomore season, he came off of the bench in all of the 29 games he played in to average 5.1 points, 1.8 rebounds and 2.6 assists in 18.2 minutes a contest... Shot .398 from the field, .224 from 3-point range and .764 from the free throw line... Posted a 1.95 assist-to-turnover ratio... Averaged 6.8 points and 3.4 assists over season's final 10 games (.525 field goal shooting).
Don't get me wrong, Je'lon Hornbeak was one heck of a player and I would have been very happy to see him finish his career in a Sooner uniform. I referred to him as the most fundamentally sound of the three freshmen guards OU signed that year. Hield and Cousins were the other two. But, the facts and his stats speak for themselves. IMHO, it's not unreasonable to assume that Odomes in particular is capable of performing equally as well his freshman season.
Booker was not nearly as versatile as Hornbeak. He was a huge asset when he was making his shots from three. Not so much when his shots weren't falling. Following a promising freshman season when he made 37% of those shots, his average dropped to just over 30% his sophomore season. I wish Frank had been able to come back this season, because we will miss his ability to score from deep and his experience. But the truth is, he was pretty much of a one trick pony who never really showed a knack for scoring off of the dribble or by taking the ball to the rim on a consistent basis.
My point is, experience at the D-l level aside, I don't see matching what Booker brought to the team as a major hill to climb. Hornbeak was a different story. He was a very versatile guard who was a more than adequate back up at the point.
