TAMPA — Thursday's news that Texans rookie QB Deshaun Watson was lost for the year to a torn ACL in practice struck home for Bucs coach Dirk Koetter, who has known the 22-year-old since well before his NFL days."Deshaun was a ballboy for us in Atlanta. His high school was right up the road there," Koetter said Friday. "Deshaun worked training camp for us every year before he went to Clemson, so we know what a great kid he is and what a great person he is. To see the success he was having, you don't wish those things on anybody. That's just unfortunate for any player at any position."Koetter said he's confident that Watson can make a full recovery, as he did from an ACL in his other knee early in his time at Clemson. "He's come back from it before. I thought the comment from coach (Dabo) Swinney, Deshaun had that his freshman year at Clemson and came back and won the national championship," Koetter said. "There's examples of that all around the league. "(Tight end) Zach Miller from Chicago is still in the hospital in New Orleans and having another surgery today. Zach's another guy we know, played for us in Jacksonville. This is a great game, a very popular game and we're all very fortunate to be in this business, but you can never lose sight of the worst part of this game, which is the injuries to players.
