Well Purdy is maybe the biggest reason they were in the NFC championship game last yr and in all likelihood will be again. . No one can really tell with any real accuracy what the ceiling will be on ANY player much less a QB. Heck Shanahan took Garoppolo to a SB . Bet you said his ceiling was low. The fact is that numerous QB's that were mediocre or their ceiling was low have WON SB's . And it was because they had good to great coaching. You think Gruden said " Yeah Brad Johnson is gonna win me a SB" But he probably said " Yeah I might be able to coach him to a SB "
