Now, with Hasty heading to Washington, Rosenberg will be the guy defenses focus on in trying to prevent Bellevue from winning a fifth straight Washington 3A title.
"We have a lot of doubters, but we've had them for a while and we still won. We play Long Beach (Calif.) Poly this year, and that will be our chance to show what we can do," said Rosenberg.
"I'm getting recruited as a free safety and as a wide receiver. No one's really looking at me as a running back. I'd prefer to play safety in college though," said Rosenberg.
His favorite is currently Washington State, with them being the lone offer, but said after that he's looking all over the Pac-10 and the nation.
"I'm interested in those schools I've gotten letters from. I grew up an Ohio State fan, and sent them some film. I like Washington too, and J.R. and E.J. (Savannah) are there now. There is a little pressure to go there."
On the camp circuit, Rosenberg is going to the Stanford Nike Camp and has been invited, and would like to attend the UCLA and Oregon camps this summer.
"I'd like to check out the UCLA campus," said Rosenberg. Rosenberg said he is in no rush to make a decision, hoping to wait it out and see what all of his options are.
As a junior, Rosenberg saw limited action at running back because of Hasty's presence, but still reeled of 740 yards and 8 touchdowns.
In the state championship game, Rosenberg ran for 3 touchdowns (51 yards, 54 yards and 36 yards) while Ferndale held Hasty in check. The game before, Rosenberg ran for over 100 yards, including a 97-yarder to seal the deal against Lynden. In what was supposed to be a matchup between the state's top two backs in Jonathan Stewart and Hasty, Rosenberg got the fun started with a 72 yard touchdown in the first quarter and his 186 yards was overshadowed only by Hasty's 6 scores.
Academically, Rosenberg has a 3.0 GPA and is enrolled in a Princeton Review class to prepare for the SAT's.
