While #1 overall pick Matt Stafford received a reported $41.7 million in signing bonus money from the Detroit Lions, ever wonder how much a undrafted free agent can expect to get?**The majority of undrafted rookies get signing bonuses of between $1,000 and $25,000. While prospects getting a bonus of $1,000 (or less) is very common, $25,000 prospects are extremely rare. Using all our sources, we could only confirm that former L.S.U. defensive lineman Marlon Favorite (Carolina Panthers) has received a $25,000 bonus this spring. **We'd figure $6,000 to $7,500 is the "average signing bonus" for an undrafted prospect, in the current market, but it can vary per team. The New York Jets, for example, almost never dole out more than $2,000 per undrafted prospect, while teams like the Vikings, Panthers, Colts and Broncos tend to be more generous with signing bonuses, hoping they can snare a future contributor by giving a draftable kid what amounts to "chump change" in the modern day N.F.L. For instance, Colts' star Peyton Manning made $18,704,320 last season (over $1 million per game) for being the leader and face of the Indianapolis based franchise. Meanwhile, on the other end of the spectrum, a undrafted rookie (Danny Woodhead) that impressed the Jets enough to be placed on injured reserve last season made $200,666 without suiting up for a game or practice. **Signing bonuses of $10,000 to $15,000 are fairly common (about 20% of U.F.A.'s get this), but anything over $16,000 is also rare. The 20,000 and above range is even more rare. As we mentioned, Favorite secured $25,000 from Carolina. And, according to the people we've talked to, only a handful have got $20,000 or more. The short list includes safety Colt Anderson of the Minnesota Vikings and quarterback Hunter Cantwell of the Carolina Panthers.
