Money means nothing to Pioli right now. We have plenty. Even with Cassel and the #3 pick we still have enough money to get a high-end player, if there was any. We could definately use Pace, but as much as I like and want Holt, we have signed 3 WR's this offseason, so he isn't an option.
Doesn't mean we can't sign more. Guys like Webb, Robinson, and Franklin probably end up on the practice squad or get cut. Copper's a special teams guy more than a WR. Engram's a bit injury prone. Getting Holt isn't a bad idea even slightly.
