Not so sure about that. An increase of 50 would be about 3.1 more targets per game, which is likely high, but 2 sounds about right, which would be an increase of 32 targets (and surprisingly make him the 6th most targetted player if he played 16 games last year). He missed 3 games and played sparingly in another 3 which someone said earlier here, so lets just say he missed 4 games instead of 6 which is a little high.
That makes no sense. A starting WR leaves and the majority of his targets go to a guy already starting? Also, D-Jax is a deep threat. His target percentage is small for a starting WR as a lot of his routes are deep. Replacing that with a more traditional WR and that new WR could get more targets than D-Jax did. This is gross hope.
Also, you are completely ingorning the coverage/route aspect. If DeSean leaves, Maclin is the deep guy - his catch % takes a big hit. If he sees more double coverage, same thing, as well as a decrease in targets.
Only the elite of the elite can have that catch % on so many targets, while getting primary coverage attention. Unless you think Maclin is Larry level, those projections are way off.
DJax was the most targetted Eagle last year. My belief that Maclin sees an uptick in targets next year is because if DJax is gone, Maclin is hands down their best receiver and best playmaker besides Shady. If they had a legit WR to take DJax's place, than Maclin's upside may be more limited, but they dont. Riley Cooper wont be stealing targets by the handful from Maclin.I didnt completely ignore the route aspect or the change if DJax leaves. In fact I said those numbers are likely too high and wouldnt count on them myself, but its just something to consider. His catch % this past year wasnt crazy, and expecting him to catch 64% next year is pretty much standard for any top 40-50 WR.
Not to mention Vick was banged up this past year and missed 3-4 games, so no reason why that wont help Maclin if both are healthy in the offseason and play an entire season.
Maclin was injured, of course D-Jax got more targets.65% is not standard. Larry Fitzgerald's % was 52%. Calvin Johnson's was 62%. 65% would put Maclin
top 6 in the NFL for starting #1 and #2 WRs (two of which played with Aaron Rodgers). It was crazy. Why? Not because he is better than Larry Fitzgerald, Roddy White, Andre Johnson, AJ Green...no...because he had the easiest time. Why? He didn't get the coverage. Why? He didn't demand it, largely because Jackson did.
Riley Cooper will not start for an NFL team on opening day, period. Most likely ever. Nor should he.
In order for Maclin to get the numbers you suggest, with no help on the other side, he has to beat double coverage the way guys like Brandon Marshall and Larry Fitzgerald do. That won't happen.
