ORCHARD PARK, N.Y. (AP) If the first day of the Buffalo Bills' rookie camp is any indication, Rex Ryan's larger-than-life personality has already rubbed off on many of the newcomers.

The rookies - from first-round pick Shaq Lawson to undrafted rookie Glenn Gronkowski - showed no fear of expressing themselves Friday.

Quarterback Cardale Jones called Ryan his long-lost father because the two share a similar playful personality. Linebacker Eric Striker wondered what the big deal was about chicken wings in Buffalo, before being informed he needs to try them.

As for Gronkowski, he laughed and teased that he's more intelligent than his famous older brother Rob, the New England Patriots star tight end.

Ryan smiled when informed of what had been said, joking that Gronkowski was dead on.
