Tiki Barber: GMs Shouldn't Sign Manziel ... 'Not Worth The Risk'

Tiki Barber says NFL teams SHOULD NOT sign Johnny Manziel ... 'cause the troubled NFL free agent is just "not worth the risk."

TMZ Sports saw the former N.Y. Giants star Thursday in NYC and asked him to weigh in on Johnny Football's prospects of being signed by an NFL team.

Tiki -- who's a Johnny Manziel fan -- doesn't mince his words, saying Manziel is "too much of a distraction."

We also asked Tiki about the situation at Baylor. Barber -- who has 4 daughters -- has a strong take on how things were handled.
