one important question is, what will be the format of ncaa's? galen is certainly doubling and sam is probably going to focus only on the 10K. galen will be measuring his efforts as much as possible.
if galen is healthy, there is really nothing sam can do to shake him. his only strategy would be to take off from the gun (if the 10K is first) and try to sneak away as galen might be reluctant to go if the pace is going near AR pace from the gun and he knows he has the 5K coming still. however at some point galen would react and unless sam can actually run 27:10 by himself, galen will likely bring him in. if it were galen from two years ago it would be close because galen wasn't showing closing speed under 60. now is a different story. they might have galen, luke and shadrack in the race and with shadrack's recent races he is getting a kick of his own. if it doddles too long sam could have two ducks to deal with.
most likely sam will have to lead to make it a 2 man race and galen will overcome him. galen is scheduled for an 800 next week and a mile on the relay the following week. his speed is only improving at this point.
