Close, but no.
The reason the Pats picked up Tebow was because they knew Hernandez was a personnel time-bomb and with their offense, if they wanted to go to the 2014 Super Bowl they needed another TE like right now. Only now, a couple of weeks later, do they know how prescient that decision was.
Also having a guy who can run the scout team to prepare for Washington, Seattle and SF is another reason.
Oh yeah one other thing... Tebow's ganged up too, but it's a different gang... one that tends to stay out of trouble. Gotta give him credit for that...
