"too tall for soccer" is something of a weird statement, given the large advantage height gives in the game. Even at high levels, some teams' strategy resvolves around having a couple tall guys (and many other teams keep tall guys to deal with those same strategies). It of course isn't everything, given the need for stamina, sprinting, and strength, which are hard to have all at once in a tall person. But its not uncommon for defenders and some strikers to be 6'8" or upward - average height in the premier league is 6'1" and creeping upward each year
