PLEASE.
4.37 with that build. 
yep, and had the 3rd fastest 100 meter time among sophomores in the nation last spring. Not running track this year. He destroyed the 6A field in the final in a Fully Automatic Timed 10.40.
Yes, this dude is definitely faster than Newman was at this age(a lot bigger too) and no reason to believe he won't continue to get faster.
Regardless of whether or not others offer you don't turn down a kid in Kansas with that type of speed. He's as fast as any kid out there in Florida, California, Texas, etc. Might not play like them but maybe he will in the future. If you're going to miss, miss on speed.
