Neither player is expected to challenge for a starting job right away and instead are part of the Raiders' youth movement. Though several draft experts had Walker tabbed for later in the draft, Oakland head coach Bill Callahan lauded the offensive lineman's size (6-8, 344 pounds) and agility (5.26 seconds in the 40-yard dash) as skills too key to pass up.
''It's hard to pass up a lineman of that size and caliber,'' said Callahan. ''This is an individual who possesses tremendous size and speed at the position. We felt he picked up his play and improved throughout the season. His best football is ahead of him.''
Walker played left tackle in college but Callahan said the team might experiment with him at guard as well.
Jolley was an All-Mountain West Conference first-team selection as a senior after finishing second on BYU with 32 receptions, 492 yards and seven touchdowns. For his career with the Cougars, the 6-4, 251-pound Jolley had 52 catches, 768 yards and 11 touchdowns. Oakland, which actively pursued free agent tight end Shannon Sharpe in offseason, is looking for Jolley to press starter Roland Williams and backup Jeremy Brigham for playing time. The Raiders tight ends combined for 45 receptions last season but averaged only 8.5 yards a catch. Conversely, Jolley averaged 15.4 yards as a senior and 14.8 yards for his college career.
''Doug Jolley gives us something in the passing game we felt we needed in terms of speed,'' said Callahan. ''What he is is a downfield receiver. He is a downfield wide receiver, a guy that can work the zones, can work the seams, can work man coverage. In addition he does have the ability to long snap, which is exciting for us to have a guy that can be a backup long snapper and give Adam Treu assistance.''
