I have Bowman, a rival owner has L David and wants to trade straight up simply because he's a Niners fan. At first glance, I thought it was a no-brainer but then the more I look at it the colder my feet get. Yes David is two years younger and has not blown out his knee yet but he is an outside guy and has the rookie from last year coming on strong to steal tackles. Bowman is inside and pretty much cleans up everything. Also our scoring rules are pretty typical, one point per tackle three points for an interception or sack. It looks to me like almost everybody projects David for 20 les tackles than Bowman but a couple more sacks and or pics. Since those are so much harder to predict and tackles are really the meat and potatoes of IDP in our PPR league with only two IDP players, am I crazy to pass up on this and just keep Bowman?
