One, he can be a versatile, difference-making player as both a ball-carrier and receiver.
And two, that won't matter if he can't stay on the field. Prosise appeared in six of a possible 18 games (playoffs included). Seahawks coach Pete Carroll was asked last week about Prosise's durability.
"I can’t tell you that I’m not concerned about C.J.," Carroll said. "He had trouble through the offseason. He was unavailable to us throughout, and there was a groin and a hammy and a wrist and the scapula thing he had. He has to show it."
Carroll has raved about Prosise's ability since the moment the Seahawks drafted him in the third round last spring. Prosise carried 30 times for 172 yards (5.73 yards per carry) and caught 17 passes for 208 yards (12.2 yards per reception) this past season.
Around Week 8, he started to look like a player who could help carry the Seahawks' offense down the stretch. Prosise had 103 yards from scrimmage against the New Orleans Saints and 153 total yards two weeks later in Seattle's best win of the season -- a Week 10 victory over the New England Patriots.
But he injured his shoulder the following week and missed the rest of the season. Prosise would have had a great chance to return had the Seahawks advanced to the NFC Championship, but he was sidelined for both playoff games.
"The interesting thing is he was very consistent at Notre Dame his last year there," Carroll said. "He rushed for 1,200 yards and caught some balls and all of that. We just have to find it, and it seemed like it was a sequence of events. He certainly is on it when he’s right, and we would have had a shot this week to get him out there again. We would have busted to get it, and he would have had a really good chance to make it, so he was that close to returning. But there is concern."
The good news for Prosise is that he goes into the offseason without any lingering issues. If he can stay healthy this summer, Prosise figures to have a significant role in the Seahawks' offense in 2017.
