One of the questions asked the scouts which rookie (other than a QB) would they build a franchise around. Jake Long showed up in a few of the guys' answers:

Green: Two spots stand above the rest in terms of team-building: quarterback and left tackle. Take the quarterback out of the equation, and I'm most impressed by Miami's Jake Long and Denver's Ryan Clady. I had some doubts about Long's ability to play on the left side, but he has held up well. Long is a player in the mold of former Broncos LT Gary Zimmerman, with the athletic ability to handle speed rushers and the size and strength to be a road grader in the run game. A big part of the Dolphins' success has been the team's efficiency on offense, and Long has played a major role in stabilizing that unit. I'd start my franchise with him.

Kidd: Without a doubt, the NFL's best teams are built from the inside out. That's why I'd take Long, who has stabilized Miami's offensive line and given the team a premier talent at the line's most critical position for years to come. He's smart, tough, competitive and skilled. Nobody expected the Dolphins to be in the hunt this late in the season, and some of the credit for that goes to offensive line coach Mike Maser and his work in Long's development.

Williamson: Compared to other positions, running backs are somewhat interchangeable. Put them in optimal surroundings, and drafting a productive ball carrier just isn't all that difficult. But left tackles don't grow on trees, so if I'm picking from this year's crop of rookies, I take either Long or Clady. Both would be excellent selections, but I think Clady has been slightly more impressive overall. He has outstanding athletic ability and a bit more upside.

Other's receiving votes were Chris Johnson and Ryan Clady. 2 and 1/2 out of six scouts doesn't sound bad to me.
