NFL coaches are nothing if not cagey about their lineup plans. It seems first-year head coach Mike Macdonald is no exception to the rule. When he was asked after their most recent practice who would be starting at right guard, Macdonald made it clear he knows who'll get the nod, but he also has no plans of sharing that information with the media, and by extension his Week 1 opponents, the Denver Broncos.Here' Scott Foster Jersey s what Macdonald shared when he was asked whether it would be rookie Christian Haynes out of UConn or former LSU starting at that spot."We have a pretty good feel for how we're going to line up next week at this point... Let's just kind of keep it under wraps and let them figure it out first snap of the game."Macdonald has to deal with a few injuries, but this is the only true training camp competition that has not yet officially been decided. So, who should it be?Anthony Bradford vs. Christian HaynesBradford was the team's weakest link up front last season and earned the from Pro Football Focus. Bradford earned a particularly poor 38.9 grade in pa s blocking. However, Bradford was only a rookie and a at that - typically not a spot you expect to find a reliable starter, at least not right away.As for Haynes, he was a third-round pick by Seattle this year but comes in more highly-regarded than Bradford was as a rookie. Haynes earned strong grades each of the last three seasons in college, including an last year.For our money we'd rather see Haynes get as much experience as he can as a rookie, unle s Bradford can prove that he's taken a big step forward from his rookie season - which is always a po sibility. Haynes should get the start against the Broncos, though.Injuries could have Seahawks' lineup in fluxWhile we don't know who will get the nod to start the season at right guard, we do have a pretty good idea how the rest of the lineup is supposed to look on paper. However, multiple injuries have the potential to throw the group into flux going into Week 1 against Denver.Aside from the as-yet officially unsettled right guard competition, other question marks for the starting units include center, where and may not be ready to start quite yet. Wide receiver Tyler Lockett has also been sitting out practice lately with a leg injury, so we can only pencil him in as a starter for now.On the other side of the ball there's weakside linebacker, where it will be either Jerome Baker or rookie Tyrice Knight, who played well in preseason. There's also a question of whether or not Rayshawn Jenkins can go at strong safety. If not it will be K'Von Wallace starting there. Finally, while he hasn't been listed as a starter as of yet this offseason, we wouldn't be at all surprised to see standout rookie Byron Murphy lining up with the ones.Here are our best-gue s projections for the starting units going into Week 1.Seahawks Week 1 projected starting lineupQB: Geno SmithRB: Ken WalkerWR: DK Metcalf, JSN, Tyler Lockett?TE Noah FantLT: Charles Cro s, LG: Laken Tomlinson, C: Connor Williams/Olu Oluwatimi, RG: Christian Haynes/Anthony Bradford, RT: George FantDE Leonard Williams, NT Johnathan Hankins, DE Jarran Reed/Byron Murphy IIEDGE: Boye Mafe, Dre'Mont JonesMLB: Tyrel Dodson, WLB: Jerome Baker/Tyrice KnightCB: Devon Witherspoon (S), Tre Brown (L), Riq Woolen (R)FS: Julian Love, SS: Rayshawn Jenkins/K'Von Wallace Phil Esposito Jersey
