Business, business, business. There is so much business for John Elway to attend. Besides his pursuit of an unrestricted free agent quarterback and others; besides trying to trade one or two of his better players; besides looking at all the prospects at the NFL Combine this week to help decide who he should take with his No. 5 overall draft pick; Elway, the Broncos general manager, has three restricted free agents to consider for contract tenders. The Broncos’ three restricted free agents are starting center Matt Paradis, part-time starting outside linebacker Shaq Barrett and backup receiver Bennie Fowler III. All are worthy of contract tenders. The question is which level. The projected RFA salaries, give or take: $4.1 million for a first-round tender; $2.9 million for a second-round tender; $1.9 million for an original-round tender.
