Falcon had the greatest range and the most versatility, even if he didn't fulfill his potential. I was right near the spot where he tripped in 1986 at the XC nationals. He had just looked back to make sure he was clear, which he was, and he looked to just be cruising in. That looked to be a remarkably hilly course too. But you're correct. He was relied upon to double up and anchor many relays to score points.
Craig is awesome in his own right, but I don't think he had the same versatility. Of course, Lincoln, the "walk-on," went on to be an Olympian and set the AR in the steeple before Jager broke it. So many great runners through that storied program, but Falcon was the best. It would've been awesome to see what the guy was capable of post-collegiately if he hadn't gotten injured.
