Dunta Robinson tried to keep his head from spinning as he thumbed through the Houston Texans' nearly 4-inch thick defensive playbook.
And, much to the rookie cornerback's dismay, the playbook gets bigger with each passing day.
"It's so big and they throw so much at you," Robinson said Saturday, minutes after signing a six-year deal worth about $10.7 million with the Texans. "The playbook is overwhelming. By the end of the day, you can barely close it."
Robinson, the 10th overall pick in the NFL draft, is the highest selection of any team to agree to terms this offseason. His contract includes signing bonuses of $8 million and is voidable after five years if Robinson reaches certain incentives.
The Texans have signed both top first-round picks, the other being outside linebacker Jason Babin, who was taken 27th overall. Houston will be one of the NFL's few teams to have its first-rounders in the fold once training camp starts next week -- Tampa Bay receiver Michael Clayton and New England defensive tackle Vince Wilfork were the only others to have agreed to terms.
