The Buffalo Bills are making their final selections of the 2014 draft Saturday, but the biggest news of the day was Buffalo acquiring running back Bryce Brown from the Philadelphia Eagles.

Brown's former Eagles teammate LeSean McCoy took to Twitter to congratulate Brown and take an (apparently) friendly jab at the Bills' current backfield:

@BryceBrown_34 my boy it's been fun... Good luck with everything and knowing what they got and knowing what they getting lol starter day 1

Brown doesn't project as a starter in Buffalo, where the Bills already have C.J. Spiller and Fred Jackson under contract. All in good fun, Jackson responded to McCoy's tweet later Saturday afternoon:

No disrespect to @BryceBrown_34 but @CutonDime25 starter day 1 huh? I think @CJSPILLER and I might wanna bet something on that! #BillsMafia
