I assume you're talking about a RFA, i.e. a guy with less than 4 years in the NFL. The minumum tender (I think about $300K) gives compensation at the same round the player was drafted. For $1.3M or so, it's a 1st rounder, for $1.8M, it's a 1st and 3rd. Don't quote me on the numbers because I can't find that info myself, but they're pretty close.
