Quinn may have been disappointed that he wasn't chosen earlier, especially considering that he wasn't even the Browns' first selection pick. But whatever. Quinn is now on his favorite team that he rooted for as a kid, and not too many NFL players can say that.
Draft selection choice is not an indicator of how a young player --- especially a QB --- will do in the NFL. It takes time, and sometimes as much as 2-3 seasons, for a rookie QB to develop in the pro leagues.
Speaking of QB's being drafted, the Raiders' #1 overall pick yesterday was JaMarcus Russell of LSU. He'll go into the Raiders training camp with tons of high expectations, and there'll be lots of pressure on him. But he needs to patient and not try to outdo himself, especially with this Raiders team.
IIRC, the 49ers drafted Joe Montana in 1979...in the
third round! And he didn't do too badly later on in his career.
