The "not a fit" mantra is a familiar refrain throughout the league, certainly not just singularly in Dallas. It's a mantra that is being repeated time and time again by teams that don't want to chance being exposed to negative attention. When it comes to signing Kaepernick, NFL GMs seem to agree that ''you can lead a horse to water but you can't make him drink.'' I think a team's level of desperation for a QB might have to be of catastrophic proportions before a team will be inclined to make that leap. At least, at this juncture, it sure looks that way.
