It might be best that Richardson acclimates quickly.
Pagano didn't sound like a man willing to wait long to try out his new toy. He said the running back will be on the field as much as he can handle Sunday against the San Francisco 49ers.
"We didn't bring him in here to, I guess, be the water boy on Sunday," Pagano said. "He'll be ready to roll."
And that should provide the Colts' offense with another dimension. Offensive coordinator Pep Hamilton has been preaching balance and the virtues of a power running game.
Hasselbeck thrived in a West Coast system with a physical running back in Seattle, and he believes Richardson's addition can make Indianapolis' offense harder to defend.
It also comes at an opportune time with the Colts losing three offensive starters — running back Vick Ballard, offensive guard Donald Thomas and tight end Dwayne Allen — to season-ending injuries in the past week.
"We've lost some guys," Hasselbeck said. "But around the league, that's what happens. You just keep trying to improve as you're losing guys, keep trying to improve, and this is definitely a huge boost for us."
