Receivers Mohamed Sanu and Marvin Jones both complimented Andy Dalton's improved arm strength and velocity, the Bengals official team website reported Wednesday. Dalton has spent part of the offseason with passing expert Dr. Tom House in Los Angeles.  

"Best I've seen him," Sanu said. "He's put a lot of work in the offseason, just seeing how he approaches it ... it's on you fast. You turn around and you're like, 'whoa.'"

"He's got a lot of zing, a lot of velocity to him," Jones said. "Especially when it matches the intensity with the way we run our routes. We run our plays in different periods and it just brings everybody up, him included. He's spinning the ball real nice."

Dalton had the best year of his career in 2013, getting 4,296 passing yards and 33 touchdowns along with 20 interceptions.
