Tough to Tackle, Paperback/Matt Christopher

No one trusts a quitter... More than anything Boots Raymond wants to be a quarterback for the Apollos. But because of his size, the coach assigns him to a tackle position-and there's no arguing with the coach. Boots rebels and almost quits the team. It seems that nothing can change his mind, but his brother Tom intercepts and teaches Boots something valuable he learned from playing football and being a soldier.
