train speed up, if it gets to 18+ make him a SF if not hes a QB or special teams player

14 just feels a little low to me for an MLB. To be honest though, from the builds I've seen from some players that have made National Teams (and ones from reasonably well performing nations), the emphasis is on skills. Basically well rounded but highly skilled individuals that pretty much sucked in every other department. You probably could get away with it in this current engine (depending on how long you believe it'll still be here and how much it'll change if it does).

20/20 Int/Cons screams QB to me! Especially if his speed is low, there's a good chance he'll cap before 18-20 speed, and that's a lot of development time before you get onto skills. Could make him kicker also. If his speed caps high, his options increase. SF, CB, WR and maybe even OLB. Most of my LBs are 17/18, 18/17 types, but I do have a 19/15 OLB (and coincidently a 16/19 MLB too)
