We might need Fred for this answer, but I would say yes, there is more contact made at Coors. Using Preston Wilson as an example since he was a guy who played somewhere else before Colorado, and somewhere since Colorado, he has: his highest AVG as a Rocky, highest HR, highest Doubles, etc... He actually had 80 XBH's one year, which will typically make teams really want you on the team if you played anywhere other than Colorado. His second highest total is 69 in 5 more at bats. He had 605 at bats in 2000 with 187 K's. His full year in Colorado, he had 600 at bats and 139 K's. He topped that total last year with 148 in only 520 at bats. I'm sure you can probably find more players to compare, but he was the first one I thought of. I think Sammy could actually stretch his career in Colorado, but the weather may not to his liking all that much.
