erghhhh i hate keeper limits, i mean, i guess i get that people want players to eventually percolate throughout the system and people fear the whole dynasty-building-business, but that's why i like keepers.... especially if you get into a ~10+ keeper league you can go and have a three year plan to develop the core of a team and when you invested a pick in the 2011 draft on strasburg and sold off your best players for waiver $$$ to get trout it's nice to see things come to fruition.
i would do it because potential suspension notwithstanding for cano (as in i'm not factoring in that possible suspension cano obviously provides proper first-round-ish production at a scarse position, i think the grindy pedroia has left a bunch of his body on the field and his stats are starting to decline from his improbable mvp year, and if you consider adding cano the equivalent of a first round pick, as long as you plan to properly contend this year / next it's worth it. if you think your team is gonna have a tough go of properly contending and keepers have a ~3-5 year window and a first round pick next year can get you a foundational piece for the next 3-5 years, then i'd look 4th dimensionally and do that instead of this trade,
so yeah, if you wanna make a run at the league this year / next and mortgage your future to do so, then give it a shot, seeing as pedroia to cano is an upgrade at the cost of that first round pick. your opponent is probably leery of the suspension and with the keeper window closing i reckon he wants to try and set himself up for the future, so it's inherent on you to decide if you wanna play for now at the behest of tomorrow or play for tomorrow at the behest of now. that's about the best way i can see it.
