Here’s an early list of upside players that I would want to build my fantasy teams with (some obvious, some not so obvious) over the next 2-5 years (in no particular order). Some of these players have not “arrived” yet, but are on their way to fantasy prominence based on their talent and situation. Some players who did well last season are not included because their situations aren’t looking as good (IE-Sidney Rice possibly without Brett Favre).
